I find it interesting that over the last hundred years or so, especially in the US, the 'hidden cause' of financial upheavals is usually legal - often something as simple and innocuous as changes to the rules for how savings/superannuation are taxed. When you think about this it makes sense, the rich pay attention to these changes, and move their money accordingly. It's like trying to stabilise a rowboat, you notice that the starboard is a little low, so you order everyone to rush to the port side... Another interesting parallel is between Apple and Germany. Apple's detractors have been screaming at them for over a decade about how they are going to lose because they don't have market share. Meanwhile, the computer manufacturers who pursue market share at the expense of profitability go bankrupt in droves ("we're making a loss on each unit, but we'll make it up in volume"). Disclaimer: I'm not German, but I do drive a German car :D
