Some people argue we send too many kids to four-year colleges who would be better off in technical schools or two-year programs.

But there’s good reason. That four-year degree makes a big difference in average earnings.

According to the Bureau of Labor Statistics, the average weekly pay of a U.S. worker with a bachelor’s degree is now $1,137. That weekly paycheck drops to $798 for workers with an associate’s degree and $738 for those with some college but no degree. And high school grads on average earn $678 a week.
