It's like a religious belief in some places. People accept the evidence of how to make a better society, in which valuable people who could contribute are actually enabled to do so and ultimately the required tax take to keep everyone alive actually goes down, but they'd literally rather not do that because helping other people offends their sense of self.
Like the nonsense of many prison systems. Overwhelming evidence that it's an expensive way to get worse outcomes, but people just can't bring themselves to pay less for a better world if it means prisons are less hellscape.
work -> to get money -> spend on the product of work vs get money -> spend on the product of work
Does work have no value? The price of any given item will increase with the ammount required to make it worth while for somone to do and not just ride the handout. Production will plumit and costs will skyrocket.
An old adage, Give a man a fish, and you feed him for a day. Force a man to fish, and you feed him for a lifetime.
Another way to think about it is as an energy system. As work is put in the energy in the system increases. The system currently has stored energy, but if you stop putting in energy and just consume it, in time you will deplete it.
