The subject is: Ron Paul dropping Keynesian economics and monetary policy into debate. A perspective expressed is that "Monetary Policy" is a subject of valid debate.
"Monetary Policy" is obscure, when you only have an hour for discussion. The complex nature and the "volume" of relationships to consider, make talking meaningfully about it a waste of time. Not even the economic environment for discussion can be discussed meaningfully in that time.
Representatives do NOT have the education nor exposure to interact meaningfully having to do with monetary policy. That's what systems of aids and departments are hired to tend to. Anything a person says about monetary policy does not uniformly apply in all economic environments; domestically and internationally. While policy changes daily to meet the needs of promoting economic opportunity in continually changing and diverse situations.
So if a representative wants to discuss "monetary policy", it is likely to obscure other issues that representative is trying to hide. Use up the debate time.
I would like to have Representatives talk about more meaningful issues though. Like how each other voted historically on Bills, and why.
