Revenue = total corporate income. Profit = revenue minus costs, with costs including compensation.

For the social justice analysis, focusing on "How much money is available for employees and shareholders?", you want revenue minus costs excluding compensation. Costs to buy materials (except in the rare case the company overpays because the vendor is the CEO's brother) are generally fixed and therefore not part of the analysis; overpaid executives are.

For the record, most of the criminality in corporate capitalism is not based on profit but on executive markup. If a company's only crime is making "too much" profit, then the solution is to buy their damn stock. (No, I'm not an HN libertarian. I'm a socialist, but also a realist.)

Anyways, as thought experiments, I have been toying with the idea of limiting company size to 150 people, based on dunbar's number, which would guarantee distributed ownership and accountability. By keeping group size small i think it's harder to cheat and waste social capitol.

And secondly, I have been thinking of requiring companies to distribute a certain percentage of revenue to employees for a tax break. Since 60+% of federal income is via earned income, it makes sense for the government to encourage this sort of income anyways. I also think this might align executive interest with their employees and help us make earned income more attractive. I am not really sure it's fair that capital income, like dividends and sale of property should be flat taxed at 15-20%, while hard working people are effectively taxed at 30-60%. ( don't forget about the employment/ SS tax which your employer pays, or in the case of a consultant they pay entirely. )
