One of the main reasons folks had so many kids generations ago was so they could help on the plantations when they became old enough. Fun fact: this is also why summers were taken off from school, when farm work was at its most demanding. Today, folks still have many kids either because of religious backgrounds (i.e. they are from a Mormon or Catholic church) or because they don’t really understand birth control, as simple as that sounds to normal people.
But how do you keep your kids motivated in school and off drugs and away from skid row? Well, back before child labor laws were made up, you made them work. Nowadays, kids are such slackers, always watching internet videos, it’s no wonder they never move out or get decent jobs, even after attending a college for four or five years. One way to circumvent this is to put them to work on your house. In fact, why not make it your entire livelihood? You could acquire broken down, beat up, old properties and renovate them, selling them for a profit. They call this “flipping” in the market.
