Unfortunately, a high school education and a college degree are some of the hardest, set-in-stone hiring requirements for most white-collar jobs (with some exceptions, of course).
Dropping out of high school voluntarily is a short-term rush with potential long-term adverse side effects.
If we take the intended audience of this post and apply the assumption that the only reason they're staying in school is because of a checkbox that needs to be filled for future job prospects, I'd say they'd be better off taking the GED exam and getting on with their lives.
I took the GED exam as a Sophomore in high school and was shocked by how easy it was. If the goal is to actually get a fulfilling education that enables you to chase your dreams and high school is the problem, go learn elsewhere. Find an interesting college that will take you, pass the GED (or entrance exam, if they'll take that instead) and stop wasting time in high school.
I think if you have a college degree, most employeers I ran into don't care for a high school education. One of the points in the article is that you can still get into college without finishing high school.
Can you get into a college? Yes. Are you equally or more likely to get into your particular college of choice? I'd want some damn good evidence of that claim.
