You are worried now about the dumbing down of America's youth?
You are way, way too late. It has already happened.
You live in a country where 4 out of 5 people can name the Three Stooges, but only 1 out of 5 can name even 3 of the US Supreme Court Judges.
2 out of 5 Americans still believe that the sun revolves around the earth.
2 out of 5 Americans still believe that the earth is flat.
(I wonder of it is the same 2 out of 5 people in both cases?)
Only 1 out of 5 Americans can name the 3 branches of their government.
