The US can't afford to make its educational system work out of everyone. I see no problem with excluding a small percentage of students so that the vast majority can benefit.
and THIS is why the federal government has NO BUSINESS making decisions regarding public education (now to find a way to get them to fund it without trying to tinker with it). The good of the many in the federal system out weighs the needs of an ever growing few.
Tes; think about your mass transit idea for a moment: no one wants to ride on an air-conditioned buss with spacious seats if they don't have to and if you live in a place with a population under 500k you would be out-right stupid to. I live in a place with nearly 800k people in the metropolitan aria and only the poorest of people would ever dream of being on a buss; the inefficiencies of time just aren't wroth it.
how is forcing mas-transit availably at the quality of a freaking school-buss going to help anything?
I live in a semi-rural zone at 700k; I gave you up to 500k... even then over 1/3rd of the US is outside of your proposal. Sure it's the minority, but it's a minority that your program could never never work for.
