Well that is an actually crucial and very well raised point King. Education and indeed parenting is indeed a form of brainwashing the difference is a parent and (hopefully) a teacher has a vested interested in improving a kids life chances. That's where their bias lies. Marketing companies care about the bottom line. Case in point Nike built a basketball court in a deprived area of I think it was NY or LA, that had a gang problem.
The idea and thinking behind it was through the use of symbols and the psychology of territorial marking. People would associate the Nike logo with the area and everyone would wear their stuff. Net result is a lot of single mothers had to go out and buy their sons expensive trainers for their sons they couldn't really afford, because if you weren't out and about wearing em, you risked having the shit kicked out of you if you didn't "fit in".
