I have an intuition that if we implemented universal basic income, the prices of necessities would rise to the point where people without other sources of income would still be in poverty. I assume there are UBI supporters who've spent more time thinking about that question than I have, and I'm interested in their responses.

(I have some thoughts myself on the general directions responses might take, but I haven't fleshed them out, and I might not care enough to do so.)
