I think this is such a massive and fundamental restructuring of the US's historical way of doing things (and the popular conception of "how it should be done") that pushing for incremental change like livable minimum wage is probably more effective in the short-run.

In the long run, if UBI continues proving its success in real-life trials and we're able to get a larger share of the population on board, I'd vote in favor of trying it.
