Because being on the show is a transaction you agree to where you trade dignity for easy paychecks, at least for the later seasons. Even if TLC is only paying them 1000 USD each per episode (minimum I could find with a quick Google), Brandan and Mary would have made $36000 so far from this season alone. If you divide that payment out through the course of a single year it is roughly $98.50 per day compared to the convienence store’s ~50cents per day.
