Obtuse, killing the US Trade Development Agency isn't going to do this country any good. De-funding Energy Star, a power conservation program, isn't going to save money.
Permit my to analogize... the first step in getting out of a hole is to stop digging.
The first step in spending less is .. you got it .. spending less.
Axing those departments would eliminate spending on those departments.
The end of spending on those departments would reduce federal spending by the amount no longer spent on them.
They posted a list of cuts, vary little of which would actually do any good (and much of which would do harm). and cutting 'entitlements' and 'pork spending' is just rhetoric. All of that is simply funding distribution, cutting it wouldn't reduce spending, only free it up for something else. That's not a bad thing as our money could be spent better but it's not saving so much as a penny.
The cuts are intended to eliminate spending.
Reducing entitlement funding is in many cases impossible because the courts have found that "entitlements" are a property right. Its more complicated than that of course but it is possible to reduce spending on discretionary social welfare programs. That's generally what is meant by reducing entitlement spending - though not specifically.
Pork: Look how many GOPers signed onto the "No Earmarks" pledge. It isn't rhetoric. Lefties believe that because they were aware that many of Obama's promises were so much hot air to secure enough votes. They just don't mind being lied to by their guy.
Eliminating spending doesn't mean shifting where the money goes. It means not spending it.
