But economies do not follow uninterrupted tracks.

r>g is unstable, and it will collapse.

It should have collapsed in 2008, but capitalism is very resilient and capitalists very resourceful and they persuaded the victims to pay the costs.

Perhaps it will not survive the current pandemic, I fail to see how it can survive the looming environmental collapse, but time will tell.

(By "it" I mean a economic system with r>g)
