The value of an Ivy League degree, especially, undergraduate, varies greatly from industry to industry. For example, the mining (oil and gas) and chemical industries in the Gulf States (Gulf of Mexico, not Middle East) tended to favor hiring new college grads at the undergraduate level from non-Ivy League schools. Their collective experience tracking the success of employees over many years revealed a negative correlation with Ivy League pedigree. The issue was a mismatch of culture.
In contrast, other industries might favor undergraduates from Ivy League because admission to the highly selective colleges is tantamount to a form of pre-screening of candidates by the colleges. In fact, the major consulting firms such as BCG, Bain, McKinsey limit their campus recruiting to Ivy League and a few similarly selective schools.
Access to the most elite Wall Street firms and some facets of politics is made much easier for those students who belong to a few specific fraternities and “secret societies” at the Ivy League schools such as Dartmouth and Yale. For these very atypical career paths, the Ivy League could be very much worth the value. But even gaining entry to those exclusive frats and “secret societies” requires wealth and connections from the students’ families. So a student without such familial assets who does gain admission to Yale and Dartmouth would be most likely shut out of those secret societies. This situation describes one form of the modern American Aristocracy.
I recall reading a report suggesting that an Ivy League education does help raise the career trajectory of URM’s from low socio-economic backgrounds, but not for other demographic groups in general.
So whether an Ivy League pedigree is worth it depends on multiple factors. Not a simple answer.
