Agreed, I certainly wouldn't touch Medicare or Medicaid. I'd also probably leave unemployment insurance as is, and this would kick in afterward.

But I think it could replace Social Security, food assistance, housing assistance, etc. And I think we could fund it by lifting the income cap on Social Security, but I'd need to run the numbers to be sure.

I'd say some disability benefits as well. Simply getting by can be more expensive when you can't do basic tasks yourself, even if you have the best universal health care possible.
