You were doing fine until you got to the ad hominem insult. Was that really necessary? And it is been a looooong time since somebody accused me of being a liberal.
But I disagree. Making money is pretty much the only reason to go into business unless you have taken a vow of poverty or have so much money you don't care if you lose all of a particular investment or are led to run a not-for-profit agency of some kind. A gazillionaire has the luxury of doing whatever he wants with his resources without worrying about keeping a roof over his head or taking care of his family. Few of us can do that.
If you happen to go into a business that you love, that you enjoy, that you can do nice things for and make people happy, then you will be doubly blessed. But those who are doing nothing but selling nuts and bolts and other stuff that people need or providing a service people have to have, even if they become bored or weary of doing it, are doing no less service for humankind. In the grand scheme of things, what makes an economy work and allows people to prosper are people doing their own thing serving their own interests. And in so doing, they benefit everybody else.
