The right answer is poverty. After visiting and working in prisons, asylums and almshouses, among others, Dorothea Dix witnessed that people with mental illnesses that were confined in those places, and treated badly, were also very poor. In fact, in 1854 she even presented before Congress a Bill for the Benefit of the Indigent Insane, which proposed the provision of federal land and funds for the creation of new mental institutions.
There are many explanations. One is that it caused many wars because countries wanted to take the resources and food of other republics who were good at agriculture. Another is that it brought the rise of things like oppression and inequality. People started getting enslaved as prisoners of war while women were often considered inferior because they couldn't be as efficient at farming because physical strength. Also, it brought separations into classes based on wealth and also gender based division with men being the "strong bread winners" while women were just "housewives", since they couldn't work on the land as strongly as men. And it also made people shorter, weaker and changed nature. People stopped getting a nutritious diet because they kept eating the same food. While hunters and gatherers would have meat, fruit, vegetables and grain.
