My take on this is, They have already ridden this horse into the ground trying to keep the economy afloat, don’t think they can keep making this dead horse run much longer. Keeping Rates low for too long just makes more people take out loans they can’t afford (MEW) at this point so they can buy more stuff from China or where ever. At some point you have to say enough is enough and come up with a better plan (Like maybe start a new Manhattan project for Energy independence).
