I don’t agree with Mankiw’s heredity argument. But I also don’t agree with Krugman’s claim that our society is grossly biased either. Consider this recent announcement from the public school system in Boston…
“Boston Public Schools honors Class of 2009 Valedictorians”
“The 37 students come from neighborhoods across the City of Boston. Sixteen of the students were born overseas, including immigrants from Albania, China, the Dominican Republic, Haiti, Jamaica, Nigeria, Somalia, Venezuela, and Vietnam.”
Perhaps Dr. Krugman can explain to us the unfair advantage of the student who was born in Somalia?
What I think happens is that high income families and families of recent immigrants both emphasize education and that is what explains the disparities in academic achievement. You don’t have to be a multi-millionaire to turn off the TV and have a read-along with your children or play a game that requires some math skills.
