That extra few years of schooling will earn you so much more money over your career.Sadly many just go for bachelor degrees which are worthless in many cases.Almost all these applicants will have bachelor degrees.The paper won't get you the job it will be how you present and sell yourself and networking skills.So certain fields it pays to have a degree.Most don't know what they want in college and get a Bachelor of Business degree etc. that covers many jobs.Most of these students are saddled with MASSIVE student debt and oh by the way the student loans are relentless in recovery and cannot be discharged in a bankruptcy.The government WANTS their money.I might go back to college someday just to graduate but I don't know.Probably years later when I retire.
