The economy objectively never did actually recover from 2008, in terms of returning to the previous growth pattern/trajectory.
Japan's economy had more or less been in the same situation since the Asian Financial Crisis of 1997.
They call this state of their economy 'the lost decades'. Growth never returned to the previous levels, and has been either stagnant or modest since, requiring massive active management from the government to keep everything from totally breaking.
... Sound familiar?
We have also been in our own lost decades, we just have about one less such lost decade than Japan.
In both cases, the only way to keep things going is to keep financializing more and more of the economy... but this results in an increasing wealth concentration gap and more volatility in financial markets.
The cure isn't really a cure, its a stopgap to prevent essentially a near total reset... but the stopgap itself is also harmful if you get addicted to it, and don't come up with a better solution.
The better solution is in fact to do that near total reset, and also set up something analogous to, or actually, a UBI.
But the only way you can do that is if you expropriate the capital owners.
So, the boom bust cycle of capitalism continues, until it breaks so hard that either everyone is basically dead (cough climate change cough)... or you have some kind of massive popular revolution.
