If you have 20 dogs they put you on a show called hoarders, you have 20 kids and your on a show called 19 kids and counting.
I'm sure they make much of their income from the show...real estate market hasn't been that great.
I used to watch (a couple of kids ago) and they built a very large house with a lot of sweat equity. Before the show they lived in a tiny house (considering the number of kids) and I assumed the show gave them the funds to built the new house.
Well different strokes for different folks. I notice their son who is 23, has 2 of his own already.
The Duggars probably don't believe in birth control, and you know what they call folks who don't believe in birth control...parents!
They also own land that is home to cell towers. Pays very well.
