Given that corporate profits are higher than ever yet only very few are benefiting from that gain, it should be fairly obvious that trickle-down economics isn't working. Why not increase taxes while limiting imports from countries with minimum wages much lower than ours? That way the lower and middle classes would actually see an increase in quality of life, not a decrease that they would see if we removed the minimum wage.

I would definitely not vote for someone in favor of that idea. I see no reason to believe that lower and middle classes here would see an increase in QOL if we started enacting trade restrictions on countries with lower standards of livings than ourselves. What you're talking about is essentially mercantilism, and it's long been discredited in economics.

That would be an interesting way to experiment with UBI, in a economic zone with sufficient UBI, you allow no min wage, no unemployment, etc...
