While, as I wrote above, what people here consider “upper middle class” is actually “wealthy”, truly upper middle class have a point. In the Chetty article, kids whose parents were low income to middle class (income up to the 60th percentile), ended up in the upper middle class (70th-80th percentiles).
These parents, whose entry to the upper middle class was, at least to them, the result of their attending an “elite” college may actually push their kids to get them into an “elite” college from fear of their kids ending back in the lower income brackets.
However
That population is only about 10%-15% of the graduates of “elite” colleges, and elite college graduates are only around 7% of all college graduates.
So “upper middle class parents who were born in the bottom 60% who attended elite colleges” are, overall, may 0.5% of all college graduates. Among the parents of college applicants today, most are Gen X. Among Gen-X, only 32.4% are college graduates.
That means that this group of “upper middle class parents who went to T20s and don’t want their kids to be downwards mobile” make up less than 0.2% of all parents whose kids are applying to colleges.
Around 20% of the parents with kids applying to college are from upper middle class. At most, 1% of these belong to “upper middle class parents who went to T20s and don’t want their kids to be downwards mobile”.
Now, that fewer than 0.2% are, essentially, ALL parents of college-seeking students who come from the bottom 60% by income and attended an “elite” college. Some did not make it to th eupper middle class, while even more made into the wealthy classes (top 20% by income).
So if we’re looking at “upper middle class and wealthy parents from lower income families who went to T20s and don’t want their kids to be downwards mobile”, they are, essentially less than 1% of all of that group.
So parents who are tiger parents for that reason are a tiny little minority of parents, maybe 1% of the upper middle class and wealthy kids have such parents. That means that any parent here would likely have known no more than one or two such families.
