This map is great. Thanks to the commenter for the link.
We see that very few of the top 1% work as computer programmers or engineers. Nope, management is the largest chunk of those in the top 1%, and after that doctors, lawyers, and even profession where you don’t expect people to become rich such as teachers and secretaries. They probably married into money; the chart is based on household income and not individual income. It's easier for a female teacher to become rich by choosing a good husband than it is for a man to earn his way into wealth through computer programming.
