Inflation rate isn't normal, it is indeed a phenomenon caused by the government itself alone to adjust their debt and won't rely on other sources anymore, also the USA has the biggest yearly budget on Defense alone, where would they get that budget? Inflation and taxes ofcourse. However, they will deny that accusations because they know more than anyone and they are just saying that inflation is caused by the increased demand of supply than services or goods being produced.
I do believe that inflation rate is a horrible thing in most nations, however USA is a bit different in that case. They increased it knowingly because they wanted to liven up the market once again during/after pandemic. Which meant they gave out a ton of money, and stopped the market from collapsing and that resulted with them being a lot better during this period. The alternative would have been preventing inflation and that would cause a lot of unemployment and a lot of people starving and a lot of rent not paid and many other horrible situations.
This is why I believe that we are definitely looking at something that could be done properly with inflation and then they could just reel it back into regular times next year without a problem. This isn't to say they should do it all the time, it just means that they did it once to help the nation and it did and now they can go back. The bad inflation is the one that happens unknowingly, this was calculated move.
The problem with this is that they are only delaying the inevitable, I understand your argument and it makes sense, however the more they delay a corrective crash that takes the economy to more realistic levels then the harder the fall will be when it happens.
At this point it should be obvious that a collapse of the fiat system is inevitable, it will not happen tomorrow of course and it may even take decades, but the longer this is delayed the bigger the impact will be when it happens, so it could be argued it could have been better to let the market crash at the time, change the economic system currently in place and begin the recovery already.
