Gabriel Zucman has analyzed the tax implications of the plans set forth by three of the Democratic candidates and has come up with this:
No surprises here: Warren and Sanders want to soak the rich but Biden doesn’t. Still, it’s interesting to see the details.
This reminds me that I’m still sort of surprised that no one has proposed a universal health care plan that’s heavily funded by a head tax on corporations. This would get rid of all the questions about where the funding would come from and would end up costing everyone about the same as they pay now. There would obviously be some additional details to work out, and you can imagine them being whatever you prefer.
This would obviously not be the best funding mechanism from a pure policy perspective, but it sure seems like it might be the best from a pragmatic political perspective.
