In my experience it typically takes a year or more of de-programming to undo each year of programming. The average Joe, when he finally finds himself on his own, has sixteen or more years of schooling to undo, and countless hours of TV. If he devoted himself to the task of unlearning all the bullshit and replacing it with actual knowledge he'd be fifty by the time he was done. There isn't time in life for this. The best hope is to awaken young people, who haven't yet accumulated more mis-knowledge than they can afford to replace.
