You seem to suggest that "all parties winning" is a random, unintended by-product of the process being ultimately profit-driven (which apparently is nefarious).
This is false. While there may well exist exploitation, the vast majority of successful businesses, especially those that are successful on the longer term, were and are successful because their profit/employee/customer value proposition is one of win/win/win.
It's important to get terminology right: It's "win" as in "win/win" situation, not "victorious forever". It means "better than the best alternative", not "best".
Is spending $8 on a milky Starbucks coffee a better value for the customer than the immediate alternatives to spending it, including not spending it? In that case, he "wins".
Is keeping the capital invested in the assets that make up Starbucks a better value for the investors than not? Then the owners "win".
And is taking a job at Starbucks a better deal than taking any alternative job available? It seems a whole lot more pleasant to me than most other low-paid, low-skilled jobs I can think of. If so, the employee "wins".
This education effort will likely make a Starbucks job even more attractive than the alternatives, for rather little money, making working at Starbucks a "win" for more people.
