I'd be curious to see what the net decrease/increase in costs would be if the US wiped out the vast majority of assistance programs and switched over to a basic income. After that, someone would need to take a stab at seeing what the net increase/decrease is from the change in incentives and general societal structure.
For mid-wage jobs, I imagine employers will reduce salaries to compensate, meaning the middle-class employee will likely net the same-ish. Or, rather, would stagnate raises for years until the salary equalizes. For people who make a lot of money and have more leverage over their salaries in negotiations, their salaries would likely not change, suggesting it'd be a government-sponsored raise.
I'm curious where the money for this will come from, what percentage of personal and corporate taxes will be increased.
