No, you didn't point out who or what causes inflation. You just asserted your ideological demand of what you think is happening, not how it actually works.

That's why you said "Before that, the dollar was largely stable", no it wasn't. It collapsed several times. It collapsed every time the US government tried to pull some scheme to print money. Instead of the government blaming itself for devaluing the currency and making the currency fundamentally unappealing, they claimed that the government needed more power to stabilize the currency.

After the Continental Dollar was debased during the revolution, the Constitutional framers intentionally required that US currency had to be gold and silver. But that means that it faces price shocks every once in a while, and the government can't weaponize it for war. The Federalists immediately set-up trying to destroy that system and they (and many other policies) were undone by the Jeffersonian Democratic-Republicans.

Later on the Whigs in congress tried to invent the Bank of The United States to manipulate the currency and were rebuked by Andrew Jackson's Democrats and it nearly started a civil war.

After that Lincoln debased the currency in the Civil War (and so did the Confederates with their currency), because it was the only perceived way to pay for it. As a result the south was economically devastated as much from it's currency devaluation as it was the war, and the north actually struggled badly economically for several years until the inflation stopped with the rise of Gilded Age and trying to re-link the currency back to Gold/Silver.

After years of progress, Progressives get in to undo it all and parasitize it. So although they didn't debase the currency, they established the Fed and the Income Tax. The purpose of the federal reserve is to stabilize the monetary system. And to be clear: it does do that. That's why we have had nearly 100 years with only inflation, and maybe 5 of those years with deflation. Deflation is the thing that the literal Fabian Socialists who founded the Federal Reserve, the State Department, the Income Tax, popular representation in the Senate, and Women's Suffrage wanted to achieve, because they wanted to have permanent inflation which they could doll out to themselves.

Bankers typically don't control nations with interest rates, money lending, and printing money. Typically because the government doesn't allow them to. If bankers look like they are having more money than the government, they get killed. This is what happened to the Knights Templar. They weren't heretics, the King of France just didn't want to pay back his loans, and the pope promised to look the other way because he wanted to lend money to France.
