Despite the fact that I read all your posts in this thread, I'll reply this one, don't want to quote so much text.
First of all, economic war is the most dangerous war as for now, just deny every import source and your america won't end up well.
I agree you that almost all of the money have some rich guys, that's very bad and everything is a result of our actions, we humans let this to happen from the very beginning. World would be better with only love and piece but we don't live like that. At some point that's good because we try our best to develop and be better than others, we develop nonstop. But also, you still can achieve very valuable things like become famous actor/singer and leave your name in this world. If you want to be another trump, then sorry but you can't. Also not rich people feel well too, most of them are unattractive, a lot of them have serious mental problems like stress and etc, you can't see that in public but you don't know what happens inside, believe me life isn't beautiful for even richest guys.
Making a country to go bankrupt will be one great achievement in life. It certainly doesn't sound positive, but I'm getting sick of getting poorer everyday because of the debt that made by other, I just want a way to get out from this mess.
What would anyone like you wanted the downfall of America. Remember that a nation stands not only as a person you know but individual people that had so many stories to tell and many sacrifices as well. I am Asian and never had any connection with the Americans but I don't even want their demise because we are all humans and just the same we all feel the same thing.
Because bankruptcy will make everything equal again, America is the big source of inequality in this world.
To bankrupt America, all you have to do is convince everyone to withdraw all their money from the banks at the same time.
Ie. what people just did with the proof of keys event, if people did that to banks... Boom!, the ponzi known as fractional reserve banking would collapse.
Of course that's not going to make your personal situation any better, in fact you would be much worse... And i can imagine the effect on the world economy considering that too many countries follow the mistaken Chicago school of economy (fast growth by debt) and its endless bubble/crash cycles.
What if it was never the same again, since the rich control huge portion of money supply, their withdrawal alone would be enough to cause a bank run, and I don't believe poor people withdraw their money from bank has any impact on the bank. Smaller bank may be collapsing, but bigger bank are the one ran by the rich, the collapse of the smaller bank would make the rich even richer too.
