If you answer no, but invest in interest-based products, you are lying. If you answer no, but invest in speculative assets, you are lying. For what it is worth, the current debt-based currency is all B.S. crap anyway. It is a useful tool to allow trade of real assets between people, however sick it may be at the moment. If you seek to gain more of that tool without producing something worthy of the use of that tool, you are devaluing that tool and it WILL fail if enough people disrespect it with such misuse.
