Given how resistant American voters and politicians are against any sort of welfare or social assistance I doubt UBI would ever be possible here. Remember the backlash against "ObamaPhones" and "welfare queens!" We can't even get mandatory paid parental leave approved; UBI would be a non-starter.

Americans are fine with low taxes for billionaires and don't mind high inequality as one of their core beliefs is that upward class mobility is achievable and they might also get rich.

You do have to imagine the political environment where unemployment is rapidly climbing among the middle class rather than the current status quo if your intent is to accurately predict the future.
