You said the C word (class) and you weren't downvoted into oblivion. Thank you, Hacker News readers, for not voting purely on political biases. Class mobility is essential for a healthy society. When everyone who starts life at one income level and almost always finishes life at that same income level you have an unbalance, neo-feudal society. We live in a world where if a child's parents don't have the income or education to take them to a doctor when they get a simple inner ear infection they can be permanently disadvantaged (http://en.wikipedia.org/wiki/Otitis_media http://en.wikipedia.org/wiki/Otitis_media). This kind of class lock-in is what was so terrible about earlier human models of cooperation and what the Enlightenment apparently fixed. Any argument against class-based discrimination is void while poor children are going deaf and ending up with speech development problems from a curable condition that very rarely causes serious long term consequences for a child of wealthier parents.
