I know a family that had 13 children. They had "the means to raise them accordingly" (basically they lived in a middle class neighborhood, drove older cars, didn't hire anyone to do work around their house - despite the father having a very high paying chief financial officer position with a large company). So... is it okay for those kinds of people to have 3-5+ kids?
