personally I believe UBI is a fucking retarded scheme entirely because of the first part of the phrase, the U. Not everyone gleams equal benefits from the scheme - Jeff Bezos doesnt need the extra whatever the fuck dollars a month - but having it applied to the whole population obviously makes it more expensive than it would be if applied to, say, a quarter or a fifth.
Are you familiar with food stamps?
I think that ALL government programs should take after their example - provide money only to people who need it (perhaps the bottom quintile of income earners in each state? that way it also corrrects for regional differences in income) and, with some obvious restrictions, let them decide how they want to spend it.
