It seems social status ultimately comes down to money

‌There are seniors who serve as alumni association presidents (mostly those in their 50s and older)
Since it's a fairly prestigious high school, doctors and lawyers are everywhere, but
the ones who end up as alumni association presidents are corporate CEOs.
They aren't owners of major conglomerates, but rather owners of mid-sized or strong small-to-medium enterprises,
yet their income level seems to surpass that of professionals.
They also donate a lot in the form of school contributions and scholarships.
The ironic thing is, they aren't even graduates of prestigious universities.
Surprisingly, many seem to have graduated from regional universities, specifically in engineering.
