The Fed does work indirectly and this is a common misconception by the General public. They don’t lower home loan rates and they don’t control what you pay on your credit card. The term linkages is a good one.
As for the short term spending plan to increase GDP by 4% proposed by Mr. Reeder, I would suggest that they could also do a short term tax cut to increase GDP. 😉 Beyond that difference, one should note that temporary changes are met with different results than permanent ones. Case in point is that check some of us got a while back from the IRS. Sure it was a little money in our pockets but did anyone change their spending habits? Probably not.
