Uh oh, better raise those interest rates. Can't have inflation creeping up. Now that the middle class is starting to get a bit of the gains, the business cycle needs to be reset.
Don't make any mistake, the middle class still isn't getting any gains.
How isn't it making any gains? Anyone who has retirement savings invested properly (in stocks, not under a mattress or in a bank) is making use of these gains.
They don't have stocks and probably not much of a retirement. Those things are reserved for the already wealthy.
