The lords want abortion to be cheap and easy because their degenerate sons keep knocking up the maids and they want the maids to get an abortion and get back to work, instead of going on maternity leave or, worse, getting married to a beta cuck and quitting to raise the kid.
Anything else is merely a happy side-effect.
Due to the misdirection, it's not quite clear who the lords and maids are in this equation. Conquest #1: misdirection is their business and they're good at it.
Nevertheless, every "democratic politics" phenomenon is in fact the lords being degenerate and applying some misdirection. You can do this transformation for all of them.
