Miles Corak found a major correlation between a father's earnings and the probability that his offspring will work at the same firm he does:
The bottom line is that about 40% of us have at some point worked for exactly the same firm that at some point also employed our fathers. But if dad’s earnings put him in the top 25% these chances are above average, they start taking off if dad was in the top 5%, and reach the stratosphere for top earners. Almost 7 out of 10 sons of top earning dads had a job with his employer.
