There is a reason why education of the working class has always been a concern for the left and why it has always been fought by the right.
You don't change class when you become educated. You may change income brackets though. College education can turn you into a lawyer or into a doctor, but it is very unlikely to turn you into the inheritor of a multi-million company.
The thing is, too often I meet militants who confuse the different meaning of bourgeois, thinking that anyone with a bit more income than the median person is from the dominating class and an enemy of the working class. That's a self-defeating mentality.
