I think the two of you might be overlooking some of the social pressure involved in taking thousands of dollars from a close friend. If I made that offer to any one of my friends, they'd turn it down every time. They might say it's impossible, or come up with some other excuse, but most of the reluctance will come from having to see me again if their idea fails.
If you changed your offer to something like, "Hey, I've got about $5k laying around, and I want to start a business, are you interested? What do you think we should do?", you'd probably see more action.
I personally think this has more to do with your friendship than the idea of your friends being mentally "poor".
