constantly been hearing about a recovery
What you have to understand is that the CB has a dual mandate.
Low and controlled inflation
Full employment
Also, support the financial system and maintain stability in reference rates (funding rates).
From the gov and fed's standpoint there is no problem. They are doing very well. Financing rates are low globally.
Global competition is forcing rates lower due to things like competitive devaluation and debt overhang. Debt overhang from previous stress in the financial system is relieved through QE and CB policy initiatives.
Raising rates puts pressure on over indebted actors in the modern financial system. If you want to support real GDP then there is no benefit*** (most are over indebted or carry substantial debt).
***This is the political opinion part of this, and where people disagree.
According to neo classical economic theories, raising rates is only necessary to cool inflation and/or disincentivize malinvestment.
This is one of the reasons that the US is so strong (and getting stronger).
The consumer can absorb massive amounts of debt, replacing huge amounts of spending with debt service payments. This is supporting unprecedented expansion in debt markets due to the success of central bank policy initiatives. (only constrained by the dual mandate).
It's kind of funny. Over indebtedness is causing debt deflationary pressure (limits inflation), and since the utilization and increase in debt is grows nominal GDP, it translates to gains in real GDP.
It's making ZIRP the thing that grows the economy.
Financialization has strengthened American competitiveness re GDP growth.
The side affect is a 'no turning back' type of situation where the debt can't ever really be unwound. Basically you have to "grow your way out" of this situation.
There are winners and losers in this, but it is kind inevitable given the developed nations advantages in the global economy.
