A/B is actually correct.
REF A) “Inflation is a worldwide international phenomenon, not attributable to any US policy or action”
Inflation is much higher globally than in the USA and it is mostly due to their own stupidity. The first reason inflation is higher in Europe/UK is not only because of their criminally insane fascist green policies. The 2nd reason is that the Federal Reserve has raised the Base Fed Rate from 0 to 3.5% in the last 6 months while EU/Japan have not raised rates as of yet. This is causing the Euro/Yen to collapse as money rushes into the USD which is making the dollar stronger.
The real bad news is the EU/Japan are F*KED. Any gueses what happens to the EU economy if they have to raise their rates from -0% to +5% just to put a stop to their currency collapse? And of course, if they do nothing lol? Ask a European if they still support Ukraine in January... LMAO!
REF B) Biden, Congress, and the Fed can act to reduce inflation via passage of laws and raising the American interest rates.
As explained above, raising interest rates strengthens the dollar and can lower inflation. However, if the CPI is running hot at 8.5% and interest rates rise to only 3.5%, you are STILL GOING TO HAVE INFLATION! As Paul Volker proved in 1980, you need real interest rates to be 5% above real inflation to stop it. Never going to happen. PASSAGE OF LAWS: Congress can pass a law tomorrow re-introducing wage and price controls. Inflation would collapse. Of course the shelves would be empty but hey, the inflation problem is solved.
