1.Yes, the Federal Reserve has enough power to stop the inflation and put it under control. A big enough interest rate hike can stop the inflation. The problem is that the politicians don't want to cut the government costs and reduce the gigantic US federal budget deficit.
This will cause the Federal reserve to restrain from big interest rate hikes, because it will become difficult for the US government to borrow money and pay debts with higher interest rates.
2.The US economy has been running on steroids for several years(money printing, stimulus packs, Trump's tax cuts). A recession might be healthy for the economy. Lots of bad businesses will go bankrupt, lots of "bullshit job" positions will get shut down. Unfortunately, the "too big to fail" banks and corporations will receive government support again.
I honestly believe that the best thing we could do right now is pressure the US government and FED to increase the rates as much as possible. If they do that, then the whole world would have to follow and do the same otherwise it is going to hurt a lot. This is why there is a good chance that we could end up with a big problem if things keep going like this, inflation can't be sustained forever.
We need it to go down a bit, maybe not 2% of course , not right away at least, but we need it to go down for sure. At the end of the day, it is all up to them, it's out of our control and we should go back to crypto, to see what we can do and that would be much better.
