I'm not saying corporations aren't greedy...they are! How does raising the minimum wage change that fact?
I'm not talking about "greed"; I'm talking about the dynamics of the system. US Government policy since the 1980s has favored employers and disfavored workers resulting in reduction of labor's share in national income (which is not static as you seem to be claiming). Further, the situation has been even worse for the median worker as high paying professions have seen their pay grow at exponential rates:
Wages for most workers have badly lagged productivity growth over the last four decades. But the shift from labor to capital has been a relatively small part of the story. Most of the gap between the growth rate of productivity and the growth in the median wage is due to the rapid growth in the pay of the workers at and near the top of the wage distribution.
The pay of the typical worker has been depressed, in part, due to the growth in the pay of high-end professionals, like doctors and dentists, and especially very highly paid workers like Wall Street traders, CEOs, and hedge fund and private equity partners. These were the big winners in the economy over the last four decades. The shift from labor to capital is, by comparison, a minor sidebar.

Note though that even that article concedes that overall labor share has fallen and that wages are 4.8% lower than they would be if labor share was the same as 1979. While the author considers this not a big deal, an increase of 4.8% wages in real terms would mean about $450 billion extra dollars in wages (personal income accounts for $18.6 trillion and wages are 50% of personal income https://fas.org/sgp/crs/misc/IF10501.pdf).
So what would an increase in the minimum wage change? It would increase overall wages, sharply increase the wages of lower income workers and have minimal price effects based on prior experience.
