...though the certainty that inflation is definitely 100% Biden's fault is a bit unjustified too.
When you walk into your grocery store and see consumer basics going up in price so dramatically, it's going to prompt the desire to blame, and of course Biden is a big target. Regardless of if it's fair for voters to blame Biden so heavily, they are and will.
Claiming they’re not responsible, or even worse, claiming that an additional $1.85T of spending will reign in inflation is beyond ridiculous: https://www.nytimes.com/2021/11/11/business/economy/biden-in...
The reality is everyone agrees: if you increase the money supply beyond demand for money, inflation will result. However, the demand for money is extremely difficult to model and is incredibly unpredictable. There's demand for US dollars all over the world, from dollarized economies like Venezuela and El Salvador and Panama - to European and Asian bond buyers - to unusual dollar demand curves at home, such as the sudden fear that gripped the economy during COVID that caused everyone to stuff dollars into their mattresses.
The model is far more complex than you're making it out to be.
Was Biden running the government response (or the Fed policy) when 2008 happened (when QE started, that many here are blaming for the inflation)? No, he wasn't. He wasn't even running the response for the first part of Covid. I seem to remember stimulus checks with Trump's signature on them.
One could fault Biden for the anti-drilling and anti-pipeline policies. But much of the blame is just "he's the guy currently there", so he gets the blame. "The buck stops here", and all that. It's unfair. But it happens to every president, and it's always unfair.
No, the Fed is supposed to be relatively isolated from short-run political influence to put a step of separation between government fiscal policy targeting the economy (the responsibility of Congress) from monetary policy affecting the currency (the responsibility of the Fed) except to the extent that the former effects the landscape that the latter targets, to maintain confidence in the currency by making monetization of debt unlikely.
This is very much not to prevent the elected officials of government from intervening in the economy. If anything, it frees them to do so, because the barrier against monetization of debt not only protects the currency, it protects policymakers from the perception that deficits will likely be resolved with monetization, which is a brake on fiscal policy that involves deficit spending.
Congress isn't a person or even an institution with a unitary head, and that's at least 5 separate Congresses, several of which didn't have even approximate unity between the two houses on the issue.
And most of the promises on that came from the White House, not “Congress” (as if there was anyone who could speak for “Congress” anyway.)
And Congress passed infrastructure bills in 2009, 2012, and 2015 before the one in 2021.
I think it's more the former, leading to a circular argument on where the blame for that 60% lies.
No, the Fed is an independent entity similar to the supreme court. The president could fire the chair and install someone new, but I don't believe that has ever been done.
