Bernie Sanders is promising "free college" to gullible millennials who have never voted in a national election, or paid a bill, and have a lot of college debt. What would they owe if they didn't work for 5 years, paid no tuition, and just sat around smoking pot? About the same. What he isn't telling them is that the return on investment (ROI) is waaaay below the same amount invested in the stock market over their lifetime. The ROI for Harvard is about $650,000; the ROI for investing $50/week for 45 years is over a million.
Huge disagreement on this depending on what you check. But I'll stick with my premise.
