You know the insult: "If you're so smart, why aren't you rich?" Of course, today it's harder than ever to break out of the middle class. And, of course, some people work because they love doing it. And then there's the matter of luck. But maybe their ideas about how to grow a business just don't work - for you or them.
The fact is that it takes more than good ideas to achieve success in today's markets. It takes being in the right place at the right time. It takes good execution. And yes, it takes a little luck, too. So don't blame them for trying. At least they're in the game.
