"Nevertheless, going by the laws of probability alone there is sure to be another crash (sooner or later) that will crush the hopes and dreams of the many like yourself that thought the party would never end."
Anything can happen, but only "if". I always an advocate of investing 10% of my investable money into physical gold (Not penny gold explorers, sorry). That's my rule of thumb of my asset diversivication. Like land, Gold also appreciate in value along with inflations, but with safe-haven hedging effect, the only downside it does not pay you divvy. AUD$500 in 1970, today AUD$1700. Much less appreciation compared to land value, but works during crisis, as people move paper assets into precious metals. That's my wealth insurance if the SHTF.
