People on food stamps have a lot of free time.

Prove it.

>Over half of individuals who were participating in SNAP in a typical month in mid-2012 were working in that month.

Let’s be generous and say that the other half have a lot of free time (they don’t, many are searching for a job while taking care of a family), and that the tiktok you saw only showed that other half. The parts of my comment you didn’t respond to may still be the explanation, rather than the sheer gluttony of the poor or something.
