Here is an excellent video that analyzes the cost/benefits of a college education.
I have a serious disagreement with the NIA (National Inflation Association, sponsor of the film) about the possibility of a high school graduate making 35k in an entry level job though. Hey, I'd almost kill for a job with that wage and I'm in my 50's. Realistically, it's more like part time at $7.35 an hour — probably under $11k a year, well under the poverty line.
The emphasis on young people putting "savings" into physical gold and silver is misplaced — what high school graduate has a good enough income in an entry level job to do that? But I'm not going to quibble with that when the rest of this piece is so well done.
