That goes for everything, you wont take a job that pays much less than the other jobs you can get, customers do the same with products they buy. In the end just a few percent go to profits for most companies, extremely few companies pay out more profits than they pay in salaries.

So all that productivity increase didn't result in higher profits either, end users mostly captured it by getting a lot of free services that previously used to cost money. International communication used to be extremely expensive but today I exchange hundreds of messages with people across the sea daily for almost nothing.
