Yes to OldUCarl, yes to FFA, but no to Harker.

The complexity of a national economy cannot be controlled by the tools available to a central bank- interest rates, borrowing, printing money. Now this may seem obvious but is an example of Ashby's Law of Requisite Variety in cybernetics (control systems engineering).

Harker says he does not have the tools, but Ashby's Law illustrates the futility of the task.

Harker says there will be a study " to better understand how poverty affects the economy".
It will no doubt tell us how poor people have less money, spend less, and generate fewer jobs from their purchases. I doubt it will tell us that poor people -when left unsubsidized- are hungry for work, will work for low pay if allowed to lift themselves out of poverty and thereby generate overall growth as well as skills for themselves.

I can think of a "Tool" they can stop using...THE PRINTING PRESS!

If only he listened to himself and got the hell out of the way by closing down the fed and returning the currency to one based on assets, not deceit.
