Eventually all financialized systems go the way of the dodo bird.
The Republic of Genoa is the classic example for this, as they had made their fortunes via trade (including slave trade) starting with the 1200s, but by the 1500s almost all of their wealth-creation had started to rely on providing "financial" services. And then they crashed. I'm also of the opinion that the UK's problems are caused by the same phenomenon, that's why they have never quite recovered from the 2008-2010 global financial crisis.
Afaik Switzerland is not yet a fully financialized economic system but it's certainly up there. The future will be interesting for them.
