<p>>1. Growing at a rapid rate over long periods of time is hard, doable and rewarding<p><i>and depends on factors outside your control.</i><p>This last is a critical caveat, and really the crux of the argument. It's not about cheating, but the limits of predictability in complex dynamic systems.</p>

<p>The plot on page 39 certainly looks like the St Paul market turned somewhere around July of 2020, over a year before the rent control, and the downward trend accelerated over the next couple of years. I'm skeptical of the authors' ability to tease out the contribution of rent control to a process that had already begun well before the alleged causal event.</p>

<p>>...which is measured in days and weeks, not months.<p>There are multiple issues that will force a lag of at least a couple of months. First, the issue of the mines that have been reported. Second, the tanker owners will want to be quite sure hostilities aren't going to erupt again. Third, while tankers that are trapped will leave, there will be a major lag while tankers that have been moved to other parts of the world get redirected back to the Strait to fill up. It will indeed be months before there is enough oil flowing to start retaining reserves again. It isn't like the state of shipping was frozen the day the war started and will unfreeze as soon as the ink is dry on the new cease-fire deal.</p>

<p>Another article from the other day contains this:<p><i>And even more importantly, China has slashed its crude imports, turning instead to massive stockpiles.</i> (<a href="https://www.cnn.com/2026/06/09/business/oil-strait-of-hormuz-iran-gas-prices" rel="nofollow">https://www.cnn.com/2026/06/09/business/oil-strait-of-hormuz...</a>)<p>Sounds like they're burning through their reserves as well. But since China's economy is more centrally controlled, it's likely they keep bigger reserves.</p>

<p>Once Iran closed the Strait, Trump's surrender became inevitable. The rest has been a combination of him slowly coming to terms with the inevitability of that outcome, and buying time to come up with a way to spin the catastrophe as a success.</p>

<p>>If the conflict ends, or the U.S. stops exporting the oil, the tanks will fill up again...<p>Not quite. Once the conflict ends, there will a lag of several months before the tanks will start filling up again. So even if it ends tomorrow, we may still have to ban oil exports for some time. I don't think there are any <i>political</i> ramifications for Trump---he has complete control over what used to be the Republican Party, and banning exports would probably actually help him with undecideds. But he will get heat from his sponsors and handlers in the oil industry. Policy-wise, Trump is a blank sheet of paper, continuously filled in by anyone in a position of power who flatters or bribes him. And the oil industry has been a major patron for him.</p>

<p>I haven't seen any articles saying "tomorrow" oil is going to $200/barrel. I have seen lots of articles predicting that once the stocks run out, the price will go to $200/barrel. The articles differ on exactly <i>when</i> that will happen. But seems like it's closer now than it was a month ago. People who are downstream of a stock, and have never experienced that stock running out, will not believe that it <i>can</i> run out until they see it. In the past, someone has always come along and refilled it before it hit zero. Maybe some deus ex machina will arrive to refill it again. Hard to see what that will be this time, though.</p>

<p>I don't think that any study on the benefits of protein intake is meaingful if it does not also take into account exercise. The effect of a protein-only diet on a largely sedentary animal that lives in a small cage is likely to be very different than the effect on a human who exercises regularly.</p>

<p>>...if they indeed are running a ponzi it would be surprising it could last so long.<p>There's a practice in the loan industry called "pretend and extend," which basically means endlessly extending credit to lendees who are behind to avoid acknowledging the loss. Remember, in Carvana's case the loan buyer only exists to take on debt, not be a going concern. I think much of the market actually realizes Carvana is a scam, they just see that it is a relatively sustainable one as long as the government doesn't step in. And they don't see that happening, particularly with the current administration.</p>

<p>My opinion, yes. But if someone said they had invented anit-gravity, then showed you a bowling ball "floating" but with a sheet covering any potential support, you'd be pretty suspicious. And if they refused to remove the sheet, and had previously been convicted of fraud, you'd probably be extremely suspicious. But it would still only be your opinion until the sheet was removed.</p>

<p>If "many businesses" operate this way, then "many businesses" are committing fraud. You can't publicly claim to be selling loans to an unrelated company when in fact you control that company.</p>

<p>See my reply to @rtpg. The short answer is that it is believed they are selling high-risk loans to a company they control, making it look like the publicly traded Carvana is some kind of miracle in the car industry while offloading the risk to anonymous shell companies.</p>

<p>They're an outlier in the industry in terms of profit per car. But they don't actually get revenue from selling cars, their revenue comes from selling car loans. So they're making the additional margin on the financing. They are also famous for not turning down loan applications. So putting the pieces together, it seems like they are selling high risk loans at a healthy profit. Which brings up the question of who is buying those loans. They don't disclose the buyers, but claim that those buyers are not controlled by Carvana or its parent. Given the history of fraud, it's hard to take those claims at face value. The suspicion is that they are selling the loans to family-controlled shell companies and leveraging the stock to finance the scheme.</p>

<p>>All that an inclusion of these new companies would accomplish is a bailout of their stockholders by pension funds and ETFs where millions of regular people shoulder all the downside risk.<p>Carvana is the poster child for this. It's astonishing that a company with a history of shady practices, and  that has yet to offer a convincing explanation for why it is not a scam, is part of the S&P 500.</p>

<p>>Can you explain what is wrong with people having different levels of wealth?<p>There's nothing wrong with it, in moderation. Where it becomes a problem is when the distribution of wealth starts diverging widely from people's expectation of what a fair distribution would be, accounting for different levels of ability and luck. Aside from this cognitive dissonance, there are also pragmatic limits on how big a disparity can be while still having a functional democracy. It's clear that truly enormous disparities in wealth, made even worse by a lack of regulation in political donation, lead to major distortions in the principle of "one person, one vote" which is a cornerstone of democracy.<p>>Or asked differently, if it is bad, should every individual have the exact same wealth?<p>No, because people have different levels of ability and experience different amounts of luck. Inequality is inevitable, and the vast majority of people understand and accept that. But they also expect that the system should at least roughly resemble a meritocracy, and that is impossible to maintain in an unregulated capital system because of the feedback loop between capital and income. Most professional sports leagues recognize this problem: once a franchise starts winning, they make more money, which allows them to buy better players, which leads to more wins, etc, until you have a league where a handful of teams can win the championship and the others are perennial also-rans. So they cap the amount of money that can be used for salaries. They are free, of course, to make as much money as they can, they just can't plow it all back into player salaries. Capital is regulated to preserve the fairness of the system. That doesn't mean the teams are all equal, there are still franchises that perform better over time than others. But it's more clearly tied to intrinsic merit like coaching systems and player development, not just going out and buying proven superstars.<p>Similarly, a person of average skill can get lucky and make a large amount of money. Having that capital in turn makes it easier to make more money. Over time, and across many such situations, capital starts outrunning merit as a predictor of someone's future income, which is socially demoralizing. That's where the US is today: a pervasive feeling that the system is rigged. To a great extent, this widespread perception contributes to the current political climate in the US.</p>

<p>There is another possibility: "they" are interested parties working to keep futures down as long as possible. When the space shuttle Columbia re-entered with a massive hole in its wing, the control systems kept it stable for quite awhile, until finally the vehicle went so far out of the control band that it could no longer compensate and it disintegrated. We may be seeing the same thing happen on a much larger system that is experiencing conditions outside of its operating history.</p>

<p>The problem is that in an unregulated capital system, money naturally flows uphill. The industrial revolution made this clear to everyone early on, and so we got anti-trust laws and progressive taxation. But over the decades, anti-trust laws have been weakened or left unenforced, and progressive taxation largely died in the 1980s.  We need to reinvigorate these measures, and also look for more structural ways to counter-balance the advantage of capital over merit in our economy.</p>
