> Nothing assumes people wanting to share.

It assumes once workers won the surpluses won't decrease.

This turned out to be false assumption, because people don't like to share, so they don't work as well if they only get part of the fruits of their work, as they would if they got most of the fruits of their work for themselves.

Today they don't generally get a share of the surplus, so by your argument they should be working even worse.

In "the west" they get less than in 50s, but they still do.

The important thing is - salaries depend on their performance and on the demand for given product/service.
