> It's good that public school exposes children to many subjects - hopefully most of them. So that they can discover if they click with one of them. The real danger is that someone never gets exposed to a subject at all. College is the place to specialize in a subject.

While some exposure is probably better on average than none, in some instances bad experiences can trip the fuse on developing an interest.

The rote nature of canned education, bad teachers, bad parents, or bullies can turn kids off of subjects they might otherwise come to love.
