Branches of US government doing their own thing?

Experts seem to be thinking that Powell/Fed are concerned only with their own issue ie inflation. They don't care about banks, or about the economy, or about the debt ceiling. The debt ceiling is a purely political issue, and must be settled by Congress, is how the attitude was framed by Jim Bianco.

Does this organization (government departments pursuing their own mission while ignoring other parts of the overall system) contribute to healthier results? or to a fractured overall government which is less efficient?
Powell in his department looks at inflation. 57% of Americans live paycheck-to-paycheck and couldn't raise $1000. Prices can't be allowed to raise beyond their ability to pay. So if a bunch of rich people need to suffer to decrease inflation we'll do that. The S&P value doesn't matter. (How Bianco framed it.)

The 57% versus stockholders. But a lot more people are stockholders nowadays than before (everyone created a retail trading app account over the past few years). Might be interesting to contrast 2008 'The 1%' or the 10%, versus the current stockholders versus non-stockholders.
