So then what is your argument? Before you seemed to imply that billion-dollar ideas are a dime a dozen. Anyone can have them. But good execution is difficult to come by. Now you seem to be agreeing with (or at least aren't arguing) the ultimate conclusion that I come to in my last comment which is that good ideas are rare. Whether anyone can have them or not is kind of a moot point if very few people actually do have…
No, I'm not saying they are rare. I'm saying this: 1. Everyone is capable of having a billion-dollar idea 2. Not everyone will actually have such an idea 3. Such ideas are still a dime a dozen because even if only 10% of the world population has such an idea, that's still 700 million such ideas. That's a lot. 4. It's difficult to prove that an idea was a billion-dollar idea and the only way of proving is likely to ei…
But besides that, it takes more than sheer numbers to make the argument you're making. Seven hundred million ideas is a lot, but it's nothing compared to the 6.3 billion bad ideas out there.

Personally, I think that good ideas take far, far more work and intelligence than you're acknowledging. Even if everyone can have good ideas, and good ideas are common, it takes work to develop a good idea into one that is worth executing.
