In poor countries there is no Social Security or pension plans. You starve when you get too old to work, unless you have grown kids to take care of you.
Perhaps the US could abolish welfare, so as to encourage poor girls to get married instead of depending on a government check? And reform the family court system so as to make marriage more attractive to men?
the government can afford to give away birth control with all the aid they get from the USA. and God knows which other countries feel obligated to give away money to other “poorer” countries. stop having kids you can’t feed.
