You just don't talk about it, try not to think about it. The pay of some employees at abortion clinics is remarkably low. Sometimes counselors are advertised for who are expected to have college degrees and are still paid not much more than minimum wage. Low prices are because of the effort to keep the procedure itself relatively inexpensive. Those people who believe that the poor need abortion desperately want to keep the price low for them, compared to medicine as a whole.
Low prices mean more sales and more money comes in.
The less employees are paid, the more profit. As for sex discrimination, counseling is almost entirely done by women, unlike the surgical procedure itself, which is overwhelmingly done by men. The first reason is for those who believe themselves to be altruistic. The second reason is traditional among those who wish to make money. The third reason is also depressingly traditional.
