I've nothing against the guy earning more than what his project cost. But I don't think it's what KS should be for. Basically, KS is here to help during the funding phase. As C. Taylor says in the video, people are pledging to make sure that he's gonna be able to keep on producing games. That's an investment, not simply preorder. In this phase, I can understand that people won't pay the real price of the product.
On the other hand, when the funding is finished, any pledge is basically a preorder. But one with either a very low price (think of all the low tiers rewards) or unbelievably high (10000$ for a game in which one of the NPC is modeled on you? seriously?). I know it doesn't seem like a real issue. But it's ruining the whole economy of the project. There's no real business plan. It's basically 'go with what you get'. And that's not a sane way to build your company's finances. There's obviously no prospective. When you're building products, it's to sell them, not to receive some sort of charity.
That being said, it seems that the game industry in its current form is not sane either and that the relationship between developers and publishers is also quite detrimental to a sincere spirit of entrepreneurship.
