There is no evidence to support that statement. Actually, on the contrary, the research that has taken place both in Canada and internationally indicates that, generally speaking, there are two categories of people who remove themselves from work. The first is women who choose to stay home with young children. The second is people going back to upgrade their skills, either going back to school or getting different kinds of skills so that they can get better jobs.
I would emphasize that we have not come across any evidence to support the claim that people go on basic income just to stay home and do nothing.
