Yep. That's roughly the upper limit of the range that I think would make sense for a nationwide basic income, and even that wouldn't fully cover Social Security

Yep. That's roughly the upper limit of the range that I think would make sense for a nationwide basic income, and even that wouldn't fully cover Social Security or lift everyone out of Medicaid eligibility. (I don't think it would make sense to actually start that high—I would experiment with lower levels, and on more local scales, to try to understand the economic effects. Even so, I wouldn't be surprised if the maximum benefit to the full economy and to general well being occurs for a Federal component of a basic income near the FPL, though.)
