Why is the US the only nation on earth where math and science are considered electives in public high school?

Um, that's not true at all. I was required to take Algebra, Biology and whatnot in high school. I hated chemistry. Granted the education system is tanking. @Vito: According to thus you only control the foofy social sciences. http://www.nytimes.com/imagepages/2010/01/18/arts/18liberal-2.html

In our state they are mandatory subjects. I don't know where you live, but most places kids have to take them to graduate.

That's really not true.

Who told you that?? I'm required to take math and science courses in my high school!

Sorry - I don't think that has any direct connection with reality.

this is about half true. after a certain point during one's education (differs based on state and district), a student will have completed the REQUIRED high school education in science. afterwards students may go to other science courses (and since there are more options it is seen as an elective)

Diaper changing is required for all the welfare queens in training.

the teachers union perhaps?...they're only concern is themselves,and making good little liberals...

The dumbing down of America has achieved its objective. The public school system is a "useful idiot" factory, churning out ignorant and gullible future criminals who will eagerly jump on the communism bandwagon as soon as it rolls into town. I know, I used to work as a public high school teacher. It made me sick to watch kids getting churned through the communist indoctrination mill all day long. And how well it worked. Public schools are an example of pure democracy in action. Every parent, rich and poor, wants their kids to get a free ride. They want their kids to get good grade for free, and they want their kids to get off the hook every time for misbehaving in school. And the community has a large influence over the local school district, so a principal can get fired if too many parents turn against him/her. So the principal has to pander to these irresponsible parents to keep his/her job. In other words, it is mob rule.
