Indeed.
The best example would be bonds. If you buy the California Bonds... the people of California may get a High-Speed Railroad within a year. They will not be able to accomplish the building of the High Speed Railroad without investor support.
30 years from now, the state of California will finish paying off your bonds. And you'll make some money.
Win/Win for everyone. Investors make money, and California citizens get High Speed Railroads today... instead of 30 years from now.
