I wasn't calling you, specifically, brainwashed
The impoverished are brainwashed to some degree in most first world countries. In America, the main difference I have noticed is that the the impoverished (generalizing of course) don't realize just how manipulated they are.
I think it's admirable and impressive what you have done personally through hard work and motivation. At the same time I think it says absolutely nothing about upward social mobility, which America is close to the worst for in the entire first world.
And yes, it's not always about money exclusively, but money plays a part in everything in the modern world unfortunately. Unless you can still go take a claim on unused land
