So, that is an interesting point you brought up regarding the psychological factor of knowing that your well-being is tied completely to your job that prevents you from making rational decisions. But we are speaking about this from the perspective of a well-adjusted (presumably) adult.
I'm going to do something I shouldn't and try to imagine myself as a teenager again (urgh), and whether or not I would have ever held down a job if I had guaranteed money to fall back on. There are times I think I would have done it, and times I could easily see myself throwing hands in the air and going home to play video games at the first sign of adversity.
The whole exercise leaves me wondering, even though I think the 'Basic Income' is an interesting idea for replacing needs-based programs, whether or not these individual choices, acted out en masse, would cause some severe productivity problems down the line. We aren't post scarcity just yet, after all.
Not that it matters. Most of us will be dead before something like 'Basic Income' ever makes it to the US. We are still hanging on to some pretty severe depression-era baggage.
