Kids in government schools are barely educated at all. They are “socialized”. And I betcha kids were MUCH better educated before the advent of federally controlled government schools which, by the way, are not Constitutional. (The States and the people never granted that power to the Feds)
Fist, just because something is not EXPLICITLY enumerated in the constitution does not make that thing unconstitutional.
As for you assumption that kids were MUCH better educated before the Feds got involved with education, I will have to flash back to the 1860"s. Why? This marks the beginning of the Civil War, and the reconstruction that was to follow. During this time the Federal government built schools in the south. Albeit segregated schools. So, one one hand [before the war] you had the states running education and there was none. On the other hand [after the war] you have the Feds building schools. Now I ask you, were the "kids" better off with or without Federal involvement in education?
BTW, just for the record, I favor charter schools and vouchers. I am no fan of our public education system.
