Cutting the fed funds rate will cause the market to rise, but also possibly inflation. Inflation is toughest on people who rely on the bank accounts for most of their savings... so mostly poor and elderly.
All the fund managers can show how great of a return they’ve had, but the real return won’t be that much.
The Fed has had this fixation with inflation going back now 30 years to Carter's days of stagflation. The Fed served us up some bitter medicine in the early 1980s and the Reagan revolution paid the price for that in the '82 elections, but it cured the damage done by Carter. But they should have a wider view than just keeping the brakes on inflation. That's important, to be sure, but so is the stability and viability of the overall system. To the extent that the Fed has influence over that, they should use it when tremulous times come.
