Their fair share? Yes comrade, they were not given their fair share. Wealth is distributed, not earned. It is the job of government to use force to distribute it fairly. And it's fair that politicians get the most since they are the ones who do the real work.
Productivity growth provides the basis for the growth of living standards; since 1970, government has redistributed those benefits upwards to the benefit of those who pay for the election campaigns and retirements of politicians in both major parties. Since 2000, in particular, wages and compensation for typical workers have lagged significantly behind the nation's rapid productivity growth. How have incomes for the richest 0.1% of Americans fared during that time?
Government redistributed? How so? BY what means was this redistribution accomplished?
The productivity vs wage growth correlation is a myth. Inaccurate.
Production is through use of new technologies which permit labor costs to be reduced. Those trained in the new technologies are more highly skilled and this are earning higher wages. Those that did not avail themselves of the education now necessary to work in the new standards are left behind.
Note the issue. "Those that did not avail themselves of education"....A CHOICE
