i think you're forgetting a LOT of the country. The trailer trash, the unfortunate in the south. Rich white suburban kids are the minority, although you may not know that if you are from there. Its true - inner city schools are horrendous and the numbers not insignificant. But did you know that despite all the hype about inner city youth that Florida has 57% greater amount of people in poverty than New York? Add up Alabama, Georgia, Louisiana, Kentucky, Indiana - there are some poor ass dumb folk being taught absolutely nada. Honey Boo Boo and the like.
Unfortunately, most people do not think about how municipalities / counties run their own school systems. These idiots are allowed to literally change the textbooks to whatever they want (when i say literally, i mean they have to make new customized printing plates for each school system - textbook companies spend hundreds of millions each year for everyone's "different" books). The only reason i am aware of this is through due diligence the old Houghton Mifflin LBO. This is how you have idiots in Ohio taking science out of the classroom because it doesn't jive with adam and eve. Extrapolate that to the poor (who grow up to teach the poor) and they can write whatever they want into the textbooks. I'm not joking,this is actually how it works. Its so fucked up you would have to nuke the entire education system as you know it - and lets see what the teachers unions and politicians would have to say.
this is harsh, but i honestly think it would be much more productive to continue import the smartest, brightest and hungriest minds than to worry too much about the backwards ass american education system. Its structurally unpenetrable and will take centuries to change - if at all. Its not our strong suit to run a good government or public education system. We do need to get back - and soon - to importing the best foreign minds that we can. That is our future "edge" as a country (or not), like it or not.
I'm hoping that the terrorism is just a temporary blip - its so imperative to keep luring the russian and eastern european and asian brainiacs over here - its our only practical hope.
