People Have Less Children to Day

People have fewer children to day because they understand what it takes to care for a child. Certain civilizations care more about their children than others. Going back a thousand years, people cared much less about their children. And we do not have an economic theory for what a world where the retires outnumber the children and te adults looks like. We don't need the free labor any more. M people are sources ofpeal, are creativity, ideas. This is progress.
