To be fair, a $150,000 watch can be re sold. High end watches hold their value incredibly well, and in some cases can even appreciate in value. Even luxury cars, which typically depreciate quite quickly, can be re-sold for a significant portion of their purchase price.
The same cannot be said of a $150,000 education, which cannot be re-sold. Perhaps in some cases a high value education can be turned into a higher value career, but that’s obviously not relevant to the hypothetical rich kid getting a film degree at Columbia.
