This sounds nice, but it's a great way to undermine the welfare state.
The strongest welfare states in the world (the Nordics) tax everyone, including nurses. And they give everyone universal healthcare, childcare, pensions, education in return.
When the middle class has skin in the game, they defend the system. When welfare is 'just for the poor', it becomes a poor program: stigmatized, underfunded, easy to gut.
That's why billionaires keep pushing this idea. The real scandal isn't that this nurse pays $12k.
It's that Jeff Bezos pays $0.
Jeff Bezos said the bottom half of Americans should pay zero federal income tax.
He cited a nurse in Queens making ~$75K and paying ~$12K in taxes saying “we shouldn’t be asking this nurse in Queens to send money to Washington.”
