If the population of a country is not working to raise their family and instead is taking money from those who do work, then that country will fail. When you allow the sloth to reproduce on your dime, bad things happen. Also, I don’t consider abortion to be birth control.
Sloth might include the unwillingness of natives to produce heirs. Abortion is the backup to failed/no contraception, if it takes the form of morning after pills. People get to think that an early on abortfacient is sort of like an aspirin after a night getting smashed. Well brought up young lady wakes up next to a guy she does not know. Despite her headache remembers she has failed to take birth control pills, so pop in a pill; also pop in pill for headache. Too bad they don’t have a pill to make the passed out guy in the bed go away.
