That leads to a beauty of capitalism though. People prioritize profit, yes, but with competition, the way to make a profit is to be appealing to people. You make a profit by providing the best good or service at the best price. This means that the people who have the goal of profits also have the goal of pleasing their customers.
There’s a quote from somewhere that goes something like this “capitalism takes the most ambitious, selfish, and capable people and forces them to stay up at night thinking about what everyone else wants”.
