Making money isn't the main point of business. Money is a by-product.... A new product has been found, something of use to the world. A new industry moves into an undeveloped area. Factories go up, machines go in and you're in business. It's coincidental that people who've never seen a dime now have a dollar and barefooted kids wear shoes and have their faces washed. What's wrong with an urge that gives people libraries, hospitals, baseball diamonds and movies on a Saturday night?
