I don't even test new web designs in Firefox; only IE, Safari and Chrome.
You might consider starting, since FF's 20% market share is approximately equal to the combined share of Safari and Chrome.
1. All else being equal, there's a positive correlation between general intelligence and ability to get into Harvard.
2. All else being equal, there's a positive correlation between general intelligence and household income.
3. Intelligence is, at least to some degree, heritable.
In other words, if your parents are wealthy then they're more likely to be "smart" and if your parents are "smart" you're correspondingly more likely to be "smart" yourself, meaning you have a leg up on the race to get into an elite school.
We might also add the following:
1. Having parents with a certain style of parenting (supportive, stable, stressing educational achievement, etc.) correlates with the sort of academic achievement that gets one into Harvard.
2. One is predisposed to use the same type of parenting style used by one's parents did and to stress the same things one's parents stressed. If your parents were abusive or negligent then you're more likely to be an abusive or negligent parent. If your parents stressed education then you're more likely to stress education as a parent. If your parents read to you as a child then you're more likely to read to your own children. Etc.
Room and board add another $10K, BTW.
Guy to whom I was responding specifically said: "$20,000 a year, supplies, housing, and additional fees not included.
assuming virtue is not correlated with parental income
Who said they're admitting kids based on "virtue"? They're admitting them based on expected future performance. In fact, I suspect they've had to lower standards for the sub-65k crowd just to juice the number to 20%. I agree with you, btw, that "virtue" (e.g. kindness, honesty, etc.) isn't correlated with household income.
For fun, here's a list of top public universities and their in-state costs (from US News):
1. UC-Berkeley, $11,767
2. UCLA, $12,692
3. UVA, $12,006
4. Michigan, $13,437
5. UNC, $7,694
6. Wm. and Mary, $13,570
7. Georgia Tech, $10,098
8. UC-Davis, $13,877
9. UC-San Diego, $12,128
10. UC-Santa Barbara, $13,671
11. Wisconsin, $10,384
12. UC-Irvine, $14,090
13. Penn State, $16,444
14. Illinois, $14,428
15. UT-Austin, $9,792
16. Washington, $10,574
17. Florida, $5,656
18. Ohio State, $10,037
19. Maryland, $8,908
20. Pitt, $16,590
So which state's two major state universities are both $20k+?
Low-income high-achieving students at these schools have close to 100 percent odds of attending an Ivy League school or other highly selective college...
"These schools" are "from 15 large metropolitan areas. These areas often have highly regarded public high schools, such as in New York City or in the Washington, D.C., area." It's the 30% of low-income high-ability students outside those metro areas that aren't heading to elite universities. Harvard also claims that 20% of its class falls under the $65k/year threshold and therefore pays nothing.
