If you saddle people with debt that can't be discharged, they're less able to take risks that may end up producing major benefits for society. Instead, they're driven to compete for safe positions that have a smaller potential upside. This results in less innovation, and it also depresses wages for people in the safe positions. Besides making the lives of people who are already low on the totem pole worse, this depression of wages for safe jobs can ultimately lead to a greater reliance on government assistance. The only winner is large established corporations who profit from cheap labor and fear disruptive innovation.
