Labor share of GDP is 69%, so capital gets 31% share. If everyone got a 45% pay raise then capital share would be 0.
If there was no capital then labor would get something like $500/year (the approximate amount produced per capita in counties with almost no capital investment).
What is the appropriate share for capital given that the current level makes labor something like 150 times more productive, and labor gets something like 100x higher wages compared to not having access to that capital?
GDP doesn't fully measure wealth. My concern is not productivity, it's wealth distribution. Productivity has risen greatly yet wages have stagnated for the lower and middle classes.
In my opinion, BOTH sides of this argument have merit.
What is often overlooked, I think, is the largish share taken by
highly-paid labor rather than "capital." Wall Street traders and fund managers are my go-to example of highly-paid labor, but lawyers, criminals, dentists (and perhaps dockworkers!) are among several other examples. (Top executives are highly paid but their role is more of capitalist symbiont than "labor.")
Labor pricing in the U.S. spans several orders of magnitude:
* $30/day -- cheapest labor, or disabled
* $300/day -- middle income
* $3000/day -- upper middle income
* $30,000/day -- today's upper income
That final group, earning one THOUSAND times the minimum, are very well off yet STILL are not in the stratosphere where America's thousands of billionaires and near-billionaires partake.
Income and wealth inequality are already major problems, and continues to rise. Yet civilization is faced with unrelated problems of even higher priority. Interesting times.
