I'll bite, even though I really shouldn't.

How do you define "average living standard", so that it would take a colossal disaster to have US reduced to that of Poland?

In terms of nominal GDP per capita, the US is around $85k with Poland at $25k, so US GDP would need to fall around 70%, which would be an unprecedented fall, the kind historically only associated with mass bombing or extreme hyperinflation.

		GDP is irrelevant when discussing the well being of the ordinary person. A more relevant measure would be median income together with purchasing power parity. US median income is just over 19 k international dollars, Poland is just under 9 k. Still a big difference but just over a factor of 2 instead of over 3.5.

		Good thing we're not talking about GDP then!
