If you don't complain, you eventually won't be able to complain. If you can't complain, you take anything shoveled to you by the government, poverty being the foremost.

Some people had good financial discipline and still fell into poverty due to business catastrophes, accidents or health problems. We need better systems to provide shields for those people, be it bankruptcy laws, universal insurance or healthcare.

Others live in unhabitable environments that can never sustain a viable economy. Until humanity finds technologies to address those environmental issues, they can never get out of poverty.

Then there are always people who are reckless and irresponsible. They are black holes of resources. Some can be educated while others do deserve to be poor. It's based their own decisions and I don't see a moral issue to leave them alone.
