That “flaw” you pointed out is the point of the infographic. It is literally just to visualize the proportion of revenue paid to employees. No one is saying that the rest of the revenue is straight up profit, I cannot even imagine how you came to that conclusion.
The revenue vs profit aspect is also difficult to measure. An example as to why is Amazon claimed it made no profit for years, because it reinvested all of the revenue it gained in addition to revenue that paid for operating costs. Are you going to believe Amazon’s claim? Most people would argue they did profit, and that reinvestment is still profiting, but that’s not how things are often measured.
