That's ignoring why they're getting assistance. Many people that are getting government assistance are on disability or are simply unable to find employment. The welfare recipient that doesn't work a day in their life is a myth that hasn't existed since welfare reform in the 90s. People receiving welfare currently have to be actively looking for work (with proof) and can't sit on their ass all day for money. They can't turn a job down or they lose their benefits. There's also the whole incentive to work.
If you were receiving money from anyone, not just the government, but one of the stipulations is to find a job would you find any job or would you find a job that's going to pay you more than the assistance you're getting? Most of the jobs out there right now are minimum wage corporate slave jobs that pay as little as possible with no benefits, shady scheduling so they don't have to provide those benefits, overworked, and understaffed. There is zero incentive to get a job like that until you're at the end of the assistance rope.
