Pocketing the money? I doubt it. I suspect it’s being funneled back to the Democrat party.
Perhaps PP sells a low dose Birth Control pill, that has a high failure rate. The customers thinking they are “safe” make lots of use of the pills, and therefore have a larger number of abortions then if they had less sex. PP gets a double benefit. Sells lots of Birth Control Pills and then gets to charge for the result of the ineffective product. Sweet way to make money!
