due the machinations of modern finance, i'm utterly unconcerned of the cost ( as long as the program is enacted at the federal level)...therefore, I don't seek to quantify anything....I just know that it's a simple program, easily financed, every single citizen benefits from it directly( rich or poor, black or white,we all get the same rate), and it does not pit one demographic against another.... it's literally equal across the board.
our system is currently highly complex, so even trying to quantify costs versus savings would be tough, to any degree of accuracy.... I can't list every program that currently used to dole out payments to citizens, let alone account for how many dollars are at stake for each program....
about the only concern i have is how many federal employees would be out of a job once enacted... and to be honest, i'm more concerned about the game of thrones finale than I am bureaucrats being employed by the government.
as for the exact amount to assign, i think it gets a lil tricky there, due to regional cost of living differences... but its a solvable equation. ..we might, for example, peg it to current poverty levels for enactment, and subsequently peg it to inflation for future calculations... i dunno.
unfortunately, i think it's a pipe dream right now... neither the establishments of the left nor the right are supportive of such a thing, for differing reasons.... but i think with time it will become much more appealing.( i'll be long dead and gone by then)
one fo hte bugger impediments against such a notion right now is that it doesn't bring with it power .... politicians , more than anything, are interested in power... division and strife among the populace brings power, not sensible and equal policy approaches.
