Couldn't we shrink the workforce in half but just banning women from working like things were barely 100 years ago?
Without women working to earn an income, they would be forced to be taken care of by the fathers or husbands. This would result in reduced consumption of resources; however, arguably, a lot of people's quality of life would improve.
They think there are too many people because of resource consumption. That is an entirely different matter from them holding jobs. If women can consume, then of course they want them to work as well.
