You won't change the system from within or via some mythical cultural shift. People have tried far longer than you have even thought about the problem, let alone possible solutions.

The best approach outside of revolution (which isn't something that will happen without radical destruction to everyday elements people truly take for absolute granted) is to break away from the system as much as possible and be as independent as you can be (homestead, learn skills, hunt, homeschool, etc, etc). It doesn't solve the problem, but at this stage it won't get solved until things get much, much worse. So take care of yourself and those close to you and that's the best you can do for now.
