That's one possibility, however there is another, or both combined which is an interesting one. As everything has built up in to a pyramid people are trying to find a 'backstop', which means they need experience to hold on to what they have. There are a few who also worked out that's what you need to do when you want more.
To create the 'backstop' they need to give the impression of 'more', which is where the compounding graph comes from. There are a few who get pulled in, but most see it for what it is. Then there are a few who have the experience and can provide it, but they will 'black box' it as most people are stupid and will try and create a new pyramid from it.
Anyone with capital would go to a development house, if they are worried about their strategy being stolen then they think their strategy is better than the developers. That means they're paying too little, which means they don't have the capital. It all balances out in the end, you get what you pay for! Will write something about the pyramid, it's a good subject!
