> lets not forget that class mobility without a degree is pretty much not possible in the slightest. While it is true that the school system acts as a filter that removes those who have almost no chance of upward mobility (those with crippling disabilities, for example) from completing higher and higher levels of schooling, we need to be careful to not reverse that observation. Attaining a degree is not going to undo the disability that limits one's economic growth. With the great push for everyone to have a post-secondary education we've witnessed over the last decade or two, virtually everyone who is capable of attaining a post-secondary education has done so. Those who are not completing those levels of schooling now are those who had no chance in the first place, and they struggle equally in the rest of their life for the same reason they did not succeed in school. That said, if you were born with what it takes to be top of the class in Harvard, but chose not to pursue that avenue of life, chances are you still have every bit of upward mobility potential as someone who did graduate from Harvard.
