If your answer is dual citizenship giving them access to banks abroad, a wealthy American can buy another citizenship.

There is nothing to stop them from just not owning a mortgage or house, since that is the thing you say will catch them.

It appears your argument is that foreigners are greedy, lazy, fraudulent, exploitative, and shameless, but Real Americans never stoop that low. Again, do you have statistics on this, or is just kind of a feeling?

Or if they do, surely there are ways wealthy "real Americans" could hide their money just as easily and defraud welfare, so this isn't really a problem specific to birth tourism.

TBC's continued existence isn't very relevant; the point was they/he have yet to build a lasting, full-scale hyperloop, despite his statement they would try. He stopped trying, and I'm fairly sure government approval is far from the only significant obstacle to making a functional and profitable hyperloop anyway.

I might even let go of the hyperloop concept, if they built something else of DC-NYC scale that beats the alternatives in a few measurements.

The Boring Company. Are you saying if Musk or his company essentially gives up on building something he hyped for years, it's not a failure?

I'm skeptical that the UX is improved much by having the app know the answer. The bank tells you what to pay, a month beforehand. The user has to get that number from the bank anyway, to be sure they don't incur fees. Your app should just pull it from the statements, not independently calculate it.

  - you can take it ~3 times and most colleges will give you the best score without penalty
  - you can use your result to apply as many times as you want
  - if you feel stuck you can still get a good score by moving on to the other problems
  - it's administered uniformly across the world
  - you don't need to narrate your thinking while you're still processing information
  - you get an objective score instead of a pass/fail that may be subjective

If the bar is that low, just use an accredited degree, certification, references, or a proctored quiz with questions like "define a linked list in < 3 sentences," and it would be just as effective at filtering the very lowest, while more pleasant for everyone involved and maybe cheaper. Crammable puzzles that don't represent real software engineering don't provide much more value than those filters would.
