mind you that there are far more radical options aswell, like major restructuring of the economic system thanks to climate change.

it seems the current economical system is having more frequent and intense crises which the market cannot solve. Who knows how long the system will be sustainable once more and more of the earths resources are economically unobtainable?

It only takes massive social upheaval to completely change the economic outlook for specific groups of people. A good example of this is the wealth many people amassed in the 20's which they lost thanks to war or revolution during the 30's and 40's.
