Lastly we would have a controlled population growth, like I stated earlier, since people in our day don’t get proper education they are stuck in a miserable pattern of having kids that don’t get education either. Just imagine an Earth that is in many levels better than what we have today, that is what our world would look like if everybody received a proper education.

This is a picture of kids who live in impoverished places but still wanted and got education. This is called a Kuito class.
