Scholarships aren't an option for everybody. This country already has a HUGE problem student debt as it is. Some people want to remove themselves from their situation. Not too many jobs you can easily qualify for and guarantee that you're gonna be in a different location.
Giving away years of your life? It's not prison breh, in most cases its like a regular 9-5 job, with awesome benefits. Granted you may have to spend some time away from family, but depending on what it is that you do, you're not seeing much danger. It's a way of life, it works for some and not for others. Its a way of trying to change your current situation, but again, in this instance along with everything else in life, things are very seldom handed to you. You get the pencils and the brushes provided, its up to you how you're gonna paint the picture.
