They do not tell us what they mean by “self-made”.
According to the Chetty article, 53% of Harvard undergraduates come from the top 10% by income, 39% from the top 5%, and 15% from the top 1%. Assuming, for now, that the distribution by wealth is similar to that by income, that is 15% of the students are from families with more that $11 million and 53% from families worth more than $2.6 million.
There are about 120,000 Harvard College Alumni, and, of them, 11% are on that list. Of Harvard College students, around 3% come from families with enough wealth to be categorized as UHNW, and 15% come from families which have over $11 million.
If only 21% of Harvard’s UHNW inherited their money, that means that inherited UHNWs are only 2.31% of Harvard graduates.
That means that at least 20% of the wealthiest Harvard graduates lose family money, and the vast majority of the wealthiest Harvard graduates are unable to substantially increase their wealth, compared to lower income Harvard graduates.
Forget about what Chetty wrote about attending Harvard not helping kids from wealthy families. If we are to believe this paper, that only 21% of UHNW actually benefitted from coming from a wealthy family, we must conclude that attending Harvard is one of the very worst things that a kid from a wealthy family can do, if they want to remain wealthy!
In short, I call BS on the whole “self-made” claim. The paper’s authors are almost certainly defining a Harvard graduate from a family which was worth $15 million who is now worth $45 million as being “self made”.
It does seem that people who write for the wealthy like handing out the title of “self-made” to as many of their readership as they can without entirely violating basic logic. The very wealthy rarely want to think of themselves as privileged, and most prefer to maintain the belief that “they did it all by themselves, with no help from anybody else”, even if, or especially when, most of the success has to do with a lot of financial and other support from their parents.
Unsurprisingly, Wealth-X has a VERY wealthy clientele…
Again, I don’t dislike the very wealthy, I just dislike pretentiousness, and when the very privileged deny their privilege.
PS. Looking at the Chetty graphs, while the poorer students do better, relatively, the very wealthy do better absolutely. So it is highly unlikely that the low income alumni would be the ones to dominate the ranks of the UHNW.
