However that is a small community geographically so I wonder how that would work on a larger more anonymous basis without the social pressures that certainly in Lakewood.
There are hundreds, if not thousands of Kollels throughout the world that work in much the same way.
I think what we see in those communities is that peoples true nature is the driving force (almost) regardless of circumstances or financial needs.
The social pressure is a fair point, but I am not entirely convinced that social pressure wont exist on a broader, more anonymous basis too.
Most social pressure is internal, not external (i.e. we tell ourselves that we are expected to conform, but in reality, that might not be true.) Not to say social pressure isn't reflective of the external norms, or that people aren't judgmental, but ultimately, someone getting Basic Income will likely feel their own social pressure, real or imagined, regardless of how anonymous it is. (IMHO)
Ultimately though, the Kollel system is a good place to start and study if Basic Income is being considered seriously, as they have 30-50 years of history and data.
