Wait until water starts to become scarce.

It won't be money. Or oil. It will be water.
That's when everything will really change… the richest will isolate themselves in their bunkers, on private islands, with everything secured and without worries.

It sounds extreme… but looking at where everything is heading, is it really that far-fetched to think about it?
