Why the plural? This is something that was very much US made and other countries have no choice but to react. This is not something caused by multiple "upper echelons of governments".
This is something caused by exactly one government - US one. What did you expect, other countries to instantly give up their economy and soverenity the moment Trump said "I hate you and seek to harm you economically"? Especially since he added multiple times "and I want to annex you, take away pieces of your territory" and then added completely baseless accusations as a reason for it?
The US government is specifically to blame here though, of course.
No discernable benefit to you maybe, but every crisis ends up benefiting those at the top as it always leads to a wealth transfer either during the crash phase, or the recovery phase, or both. See 2009 crash, Covid, etc.
Your leadership doesn't work to serve you, they work to serve themselves and the elite. People keep calling Trump a stupid bafoon but how come this stupid bafoon keeps getting richer and richer all the time if he's as stupid as people think him to be?
To whit, how much are you willing to bet that after Trump's mandate is over in 4 years time, both Trump, Elon and all his other cronies, will walk away with a bigger net worth than the one they came in? So no, what you see as stupidity now on the news is actually a carefully orchestrated multi year enrichment plan for the elite covered in bread and circus to distract the plebs, that will become evident as time goes on and events unfold.
1. Launch TRUMP and MELANIA cryptocurrencies to get a few hundred millions of dollars of cash. (and possibly also get some cash from the "First Buddy" Elon Musk)
2. Announce tariffs, and in general cause chaos, crashing the stock market.
3. Buy the dip.
4. Revoke all tariffs.
5. Profit.
Humans are not good a thinking.
