A company attempts to maximize profits while reducing labor costs. An employee attempts to maxamize profit from their labor, which is a fairly static quantity.
New tools can come out that enhance productivity, but that only sets the baseline productivity that much higher. Wages rarely increase to match a jump in productivity.

For most of the last century, wages and productivity — the key measure of the economy’s efficiency — have risen together, increasing rapidly through the 1950’s and 60’s and far more slowly in the 1970’s and 80’s.
So in this regard, Turing_Machine is indeed correct that wages have historically followed increases in productivity. My remarks were imprecise, the word rarely should have had an asterisk to a footnote that states that rarely means within the last decade or so.
But in recent years, the productivity gains have continued while the pay increases have not kept up. Worker productivity rose 16.6 percent from 2000 to 2005, while total compensation for the median worker rose 7.2 percent, according to Labor Department statistics analyzed by the Economic Policy Institute, a liberal research group. Benefits accounted for most of the increase.
