I've been thinking about it ever since, particularly that money usually flows between these 3. The exponential growth required for compound interest to work is only possible in a shortage. Stocks in companies follow a contract-expand business cycle. Governments grow linearly at best. But property has been increasing exponentially due to an increasing population.
I fear the day when companies realise that they'll make more money by starting a war, which would devastate governments and property. Many people of a similar age are getting married and buying houses, but I don't know feel that the future is stable enough to make either of those decisions. The kind of house I'd want now as a single guy is different to a house that would be suitable for kids (in the right school zone), or a house for retirement. I think the only safe investment is philanthropy: give it all away, and if I'm still alive, hope that some of those people I help now will be able to support me in my old age after economic, political, and environmental disasters strike.
