I would say part of the reason the USA job market is such a mess right now, is because of said consolidation. When many industries such as Tech are dominated by a handful of high profile companies and they all conduct layoffs around the same time (no collusion here!) it creates an outsized downwards push to compensation and swings the balance of power significantly towards employers in terms of hiring.
I think at a minimum UBI should be employed as a form of just keeping the general public content by putting a floor to the standard of living, I mean what could go wrong when you have lots of frustrated, unemployed or underemployed people, some of whom have tech skills and access to firearms. Also, since the bureaucracy to administer the existing safety net can be haphazard they should be all for UBI since it will remove those layers and return the authority with the associated resources to administer them at the choosing of the individual. And while some may choose to abuse UBI, I think the positive impacts it would have on the majority outweigh the downsides. It reminds me of how the USA treated German prisoners during WW2, which was like a UBI scheme that revolved around food. If you were willing to work, you got to eat the same meals as US soldiers. If you weren't, you'd get something spartan like a loaf of bread and all the water you wanted.
