How much more does the “average” college grad earn over a lifetime than someone with only a high school degree? (The current number appears to be about $1 million.)
( from the article)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

So?......How much more over a lifetime does someone with an IQ above 115 earn in a lifetime with or without a college degree?

Charles Murray's work points out that the minimum needed to have any reasonable chance of graduating from college is an IQ of 115 and much higher for the STEM courses.

Intelligence and drive ( not the college degree) are likely the key ingredients in how much a person earns.

Wintertime, long time since I’ve seen you here. ;o)

In my experience, persistance is more important than intelligence in being successful.
