On HN a story counts as a dupe if it has had significant attention in the last year or so. If it hasn't, a small number of reposts is ok.

It's not really surprising that the heart of the tech industry (which drives a large part of the modern economy) would have very wide disparity between service workers and highly skilled specialists working for companies making massive amount of revenue.
I'm not an economist, so feel free to enlighten me further on my speculations.
(edit) I should add this is by percentage. A recent study says the percentages have stabilized for now.

In relative terms the earnings growth was even more dramatic -- the upper class grew 27% larger whereas the lower class only grew by 14%.
There are more people moving up than down.
I think a more telling study would be on an individual basis. Someone earning X in Silicon Valley 20 years ago is earning Y today.
Mucking up their perfectly good business models with salaries.
