I have bad news for you. Those workers who demand 40% wage increases and 32 hour work weeks will be "easily replaced" by auto factories in the South who have right to work laws.
This is a description of the status quo of capitalist competition, but is not a fact of nature. We can arrange our economies to work in cooperation with one another, rather than in competition. Competition is used specifically to depress all worker wages for the benefit of the ownership class, and we do not have to accept that at face value.
