> The fact of the matter is, mobility is necessarily antagonistic to equality. Every student who moves up pushes another one down. These values are in direct tension, and yet no one seems to pause for a moment and really critically evaluate what we’re asking for. If your interest is in promoting equality then you should agitate against mobility, as true mobility will result only in more outliers – both above and below the mean. If instead you are concerned with simply providing a better quality of life for the most possible people, then you should focus on redistributive economic systems that ameliorate the effects of poverty and create a downward pressure on the wealth of those at the very top. Then you can allow education to go back to being education, rather than seeing it constantly as an instrument of economic manipulation – a role for which it has proven totally unsuited.
