The only benefits that I think would have to stay, are those with “unlimited” downside, like healthcare.
UBI can potentially replace specific benefits for housing or general living expenses, but it can’t really replace healthcare.
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.
