I have heard this criticism about the current school curriculum quite often, and have tried to get the attention of the relevant people for it. It's a multifaceted problem though, with no clear "fix" - for some other people, it is as much stubbornness or ignorance as it is pressure.
The second half of the study is intended to provide more room for this experimentation, or exploitation, depending on the specific subjects and personal ambitions.
Intended. Whether or not they succeed... Tja
