2. not paying his employees or suppliers enough (taking “excess” money from them)
OR
3. both
CA Renter, your argument false (though it has not always been so, in many periods of history, wealth was generally accumulated by stealing it by force)
If case 1 is true, you should start a company and undercut his price, get all his business and you will be the rich one.
If case 2 is true, you should start a company and undercut his price, since you can also pay your employees and suppliers as much as he case, in which case you will get all his business and you will be the rich one.
In a system where competition is free that competition holds margins to reasonable amounts. For example, think the price of oil is high right now, think oil companies are making out like bandits? Go start finding more and you will be the rich one. Problem is, that’s a really expensive thing to do right now (drilling equipment is very expensive for example, because the market will pay a lot for it), and you’ll find that the margin you think is there isn’t nearly as high as you’d expect.
