You keep claiming there is a moral problem with giving people enough of a basic stipend to actually live out of the gutter.
In the richest most affluent society in the history of the planet.
In a society where it is organized so a handful of people control more than 50% of the society's wealth, and it is also organized so the minimum wage has stripped is no longer even sufficient to work FULL TIME and get above the poverty line. In a society where a family owns the largest employer in the country and sits on $Billions of wealth while they pay so little that a substantial number of their employees qualify for food assistance.
Who is freeloading, the billionaire owners taking massive tax breaks and paying less than their office workers, or the minimum-wage laborer who must "take" government assistance in addition to his pay merely in order to not starve?
A society can rightly be judged by how it treats it's lowest members.
A moral affluent society would organize itself so every single person has a minimum of food, housing, healthcare, and education, even if a few were freeloading.
Instead, you attempt to justify refusing to feed and house people because a few might freeload. Or, if not refusing, to implement massive government bureaucracies, which 1) are both costly and 2) are proven to make worse outcomes and 3) are even more easily defrauded, merely to make sure all the lowly workers who cannot get a leg up are suitably shamed and monitored, lest they receive just a little too much.
And do not start on how some will waste UBI it on alcohol or drugs. The rich also waste their lives in the same way.
While you stand on your moral high-horse, you argue for the most immoral actions.
Oh dear, it's a QED, isn't it? Also please look after yourself and merry Christmas.
