Why? Because a university education costs money. Having a home costs money. Eating food costs money. Travel costs money. In the US health care costs money. As a society we are driven to pursue wealth in order to be comfortable.

Additionally not very person shares the same morals and values. We all have different ideas of what is acceptable vs not.

That all being said, my dream life is living in a tiny house in the woods. I would love to live off the grid if I could pull it off. I dont think the way we live now is the best.
