Ok dingbat.
First off, inflation and price increases are not the same thing. Inflation is the result of the federal government printing money faster than the rate of wealth creation. The Fed manipulating interest rates has nothing to do with inflation. Price increases are the result of increased costs associated with bringing products/services to market. Prices will change as the related supply/demand components within a market change.
The rest of my response will be assuming that you are wanting to discuss price increases (groceries cost THIS MUCH now!!!???).
Do you realize that the Fed manipulating interest rates can only affect the DEMAND side?? Current price increases
ARE NOT being driven by the demand side (demand for consumer goods has been freefalling for years now... WE ARE IN A DEPRESSION for goodness sake!)... Current price increases are actually being driven by the SUPPLY side, driven by the radical change in national energy policy (ideologically chasing solar panels and windmills). IOW... low supply (read: shortages), due to radical "green" national energy policy, is in a general sense pushing prices upward.
What the Fed is doing, underneath their pretending that the demand side is the issue, is trying to "manage the transition" from coal/oil to wind/solar. "Managing the transition" unfortunately involves purposely pushing demand as low as possible (hence the increased interest rates DURING A DEPRESSION), pushing demand down in line with the purposely lowered supply. No amount of Fed interest rate manipulation can address the root cause of these price increases, which is the ideological (idiotillogical?) national energy policy that is crushing the supply side.
Enjoy the "new normal"!
TLDR: Democrats are pretenders, in this case pretending that demand side = supply side.
