One of the troubles with this kind of reasoning is it kind of assumes peoples behaviour will remain much the same so someone on a $50k salary will keep at it but maybe with some basic income added and some tax removed and similarly for someone on welfare.<p>And maybe that will be roughly true initially but people change their behaviour and maybe the guy who would have done the $50k job if you give him say $300&#x2F;week no strings attached will say hey, why slave away when I can go to Bali and surf and smoke joints.<p>We had something like that when I was a kid - the somewhat socialist UK government brought in generous untested welfare and some people used it to hit the beach in Spain and then the remaining workers paying the bills objected.
