Some people just want high social status, they really don't give a shit about 'excellence', unless excellence is absolutely necessary to achieve high social status and it isn't - going to the right school and working at the right job at the right company is enough.
If you know anyone with immigrant parents who value 'education', you already know what they actually value is high social status regardless of everything else, including the child's happiness.
What you spent a whole lot of words describing is a narrow case of a more general human phenomena that has a name - tragedy of the commons.

There isn't a cure, because most people don't want a cure - that's why it's a tragedy :)
