In the world of business, there are naturally people who do sketchy shit to acquire wealth.
But the majority of folks do so by following the golden rule of making money.
To make more money, bring more value to more people.
I have more positive feelings toward my local used book store than I do Amazon. But Amazon has received much more of my money because I must place more value in fast shipping, eBooks, and streaming services.
In a restaurant, a server tends to make more than a dishwasher because they have more impact on whether customers enjoy their dinner and whether they want to return or not.
Want to make more money? Bring more value to more people.
