On that last point... an analogy When the microfinance exuberance started dying back about 5 years ago, I heard the following interpretation of micro-credit:
Poor rural people need credit because they can't save. They can't save because they owe their neighbours a moral debt.
Jennifer really needs $50 to pay her kid's dentist bill. She looked after your grandmother, when she was sick and you were away. You owe her (and love her, you're friends).
If you have $50 saved, you will get requests that cannot be refused. Everyone is broke and everyone owes eachother favours. Debt is the only way of getting a lump sum. The critic concluded that saving with a (big) negative interest rate is a bitter pill, but better than nothing.
Fast food franchises sound like a great idea, if they aren't too failure prone. You lock up illiquid assets. You can give family members jobs, if necessary/appropriate. The bad idea side effects of this is that businesses can potentially lose money as well as value.
The spanner in any such system will always be debt. You can lock up all your assets but if you have assets to your name, you can get credit and spend those assets regardless.
