Is Every 18 Year Old High School Graduate Worth $30,000 A Year?

If we made the minimum wage $15 per hour, that works out to about $30,000 a year. Is every 18 year old high school graduate capable of generating $15 per hour in revenue on any job they might get? My guess is that many of them are not and will not get a job when they graduate. So when will they get a job? Who knows. Maybe they will never get their first job and will never enter the world of work.

In fact, the WSJ recently reported that many college graduates barely make what a high school graduate makes:

"The median wage of an American with a bachelor's degree was $48,000 last year, far higher than the $25,052 earned by those with only a high-school diploma. But the lowest-earning quarter of college graduates make $27,000 or less."

So if many college grads cannot make $30,000 per year, how is it possible that each and every high school grad will? They probably can't
