Yes, it is worth it to get a college degree -- the numbers prove it. Here's an overview of studies that confirm the college bonus: each year of college adds about 6-10% of annual income. And people earning higher incomes are more likely to have jobs with good benefits, and that means decent health care coverage that can lead to better health.
Apparently such studies don't always factor in the cost of going to college or those darn loans. Still, whether we like the system or not, there are undeniable advantages that come with the diploma.
