If you're looking at it through Keynes's perspective there's not a lot of investment that the highly-paid tech workers actually carry out with their total comps, many of them just save most of it in view of early retirement. According to Keynes that's bad, it's just money left not doing anything in view of the famous accumulation.
Supposedly, the money spent on those very high comps would be better spent by the companies themselves carrying out their own investments, and if not successful in doing that then those companies should return the money to the shareholders so that the latter would carry out their own investments. In either case, there would be higher chances of accumulation.
