Welfare pays fairly low wages, and comes with no means of advancement. So voluntary welfare dependency is, very literally, choosing permanent poverty. Unless of course, with the conservative attacks on collective bargaining and allowance of sub-poverty level wages (or, extreme exploitation), even working won't sustain you. Which is the typically the case, because welfare is, in a regular economy, a
support system for workers.
There's also the issue of qualifications, being that TANF is for temporary aid.
So on one hand, welfare in lieu of a job is insane, with no evidence to say it's anywhere near a normal occurrence. And on the other, it's astounding that you think cutting welfare would better the situations of those receiving it. .
