To actuallly KNOW anything for yourself, you have to go with personal experience. Curently, you're living in someone elses houses, spending someone elses money, and you have no worries. They're required to take care of you til you're 18. Odds are pretty good they'll take care of you after you're 18, and until you're living on your own.
When you're actually living on your own, fending for yourself, and don't have other people to rely on, things look an awful lot different. When someone starts dipping in your pocket to pay for someone elses cost of living who's simply sitting on their ass doing nothing but collecting a fat unearned check, again, things are going to look a lot different..
Wait til you actually have to make a *choice* between food and gas because there's even MORE money being yanked out of your paycheck to cover someone elses health insurance, someone elses rent payment, someone elses gambling habit (Yes, a very large majority of people on welfare have gambling problems - guess who pays for them?), etc..
Eventually, you're going to end up downright pissed off and change your entire way of thinking, and it's going to have nothing to do with any links you can find on the internet.
Right now, you have ZERO worries - your ass is covered - by someone ELSE.
