All evidence says it does.
Crime rates in poverty are double those without. And if people get out, they stay out.
I disagree that it's the only solution, though i defiantly agree that it's part of the solution.
Particularly with a flat fee. $180 is a huge amount to a poor person, but barely registers for a rich person.
The issue with health care, is both that costs are not equal, and not optional. You can't just choose to not buy the million dollar life-saving surgery, and you can't afford it on your own. So unless we decide to let people die, we need a mechanism for the healthy to pay for the sick.
Also, how you improve the free market is to just give people money. Then they can buy what they want.
Universal basic income is very much a free market approach.
Why not both?
Modern society has drastically improved with everyone knowing how to read. Something you do before highschool. And even with the lowest paying jobs need to know how to add up money and give change.
Buying people is slavery.
Freedom would be the other way around. Where bosses are the ones who sell jobs, and workers can choose to take it or go somewhere else.
