After high school, I got a job doing construction work - I was treated badly and I felt a lot stupider afterwards :) Seriously, there have been a lot of studies which have shown a modest (temporary?) increase of IQ for people living in an "enriched" environment. ask google. Presumably, an "enriched" environment is one that is similar to the environments of high-status people. A job is an important part of one's environment, but so is living in a "low-status" home, or going to a "low-status" school which I think would have a similar effect. (I'm using quotation marks for low-status because I feel that these terms imply moral judgements that I don't share) Note that I also mentioned the importance of having low-status ancestors - and IQ has been shown to be heritable.
