I agree to a point. In normal circumstances I'd say the same thing. But don't forget the Great Depression was followed by a world war. And our next world war is our last. No one will gain from it. I don't know how leveraged those banks were in 1929, but I do know right now if one of the big banks go they all go, ATM stops working. Some of them have OTC exposure which is more than the GDP of some countries.
It's also hard to ignore commentators like Dr. Paul Craig Roberts: https://www.paulcraigroberts.org
He can say it much better than I can.
This time is really different. We have this perfect storm of political and economical instability that's brewing. US is trying to assert itself while it's failing, Russia and China are having none of it. As a direct result of US foreign policy there is now a second financial system which most of NATO signed on for. Russia and China now decides who gets sanctioned. Not the US. So the group of people that owns the banks, media and military industrial complex is about to lose at least one leg of their empire. The only way to protect it is to use the other two to try start a conflict.
Switch on your tv, see the European migrant crises ? US foreign policy at work. Ukraine ? US foreign policy. Europe is paying the price for US foreign policy again and again and again. And they are getting very tired of it. Ukraine cost the German economy over $4 billion so far! Heaven alone knows what the migrants are going to cost in the end. That is why most of NATO signed on for CIPS. I would not be surprised to see NATO break up and that is very much against US interest.
If NATO is at war then obviously half of Europe and the rest of the world can't storm over to Russia and China to do banking. The BRICS are already going to use that system by default which means 40% to 50% of the worlds transactions leaving the current financial system. It's a major fundamental shift of the balance of power in the world. If NATO countries use CIPS it be almost 80% of global transactions going to the east. It will cause massive disruptions in the western financial systems.
There's this huge financial incentive for the US to start WW III here. They can only benefit at this point, nothing else to lose.
This is a truly a dangerous time for humanity.
