I’m not sure why you’d place the blame on capitalism for this set of problems. If the reward were status or sainthood or whatever else, enough people would still be sufficiently motivated to mistreat each other. That the reward is “profit” in the form of some government money tokens doesn’t seem particularly important.
If you look at the food in the US for example one of the most distorted elements is the abundance of high fructose corn syrup - because the government subsidises it.
