&gt; Where are you getting that from? The median personal income is very close to 30K. The median household income isn&#x27;t even 56K.<p>The data is clearly sourced it the wikipedia article. Your data is either old or just wrong.<p>&gt; Furthermore, why are you including cost of living for college students but not for workers when calculating the opportunity cost?<p>That&#x27;s a fair point. You will still incur costs that you wouldn&#x27;t otherwise, like books, etc.<p>&gt; If you plan on choosing a major that pays better than average<p>Where is the evidence the increase in earnings is the result of the degree rather than selection bias? Correlation is not causation.
