Wages are naturally bid up to a living level, or the entire workforce would die and the wealthy would suffer a lower standard of living due to less productivity. We all know, a happy worker is a productive worker. That is why capitalism replaced obvious slavery.
Slavery didn't cause the workforce to die either. Some people will work 80 hours a week in a sweatshop if they feel that is their only option to stay alive. That doesn't usually lead to a "happy worker" though.
The United States was able to become the economic powerhouse of the world with minimum wage laws and a populace that wanted a relatively high standard of living.
