Buying a share of a good business is better than buying a share of a bad business. One way to do this is to purchase a business that can invest its own money at high rates of return rather than purchasing a business that can only invest at lower ones. In other words, businesses that earn a high return on capital are better than businesses that earn a low return on capital.
