I think all that you're really voting for is where the cuts are made and where the taxes are increased.

Well that is one way to describe national economic policy!
I admit that wasn't my finest moment!
I suppose what I meant was that it's a question of taking a little bit more from here rather than there, just to make it look like your doing something different. My guess would be that if any one of the main parties stayed in power for more than 2 or 3 terms, they'd end up having to switch their policy to whatever the others would do if they got into power. Or at least they'd like to do so, if their egos didn't prevent them. I guess that may be why it's a good thing to change every 2 or 3 terms.
I see political economic policy being run like trying to balance a ball on a flat board you're holding in your hand. The ball starts to run to one side, so you tilt the board slightly the other way. The ball then rolls towards the other side, so you tilt it back again. Sometimes it gets quite close to the edge, but provided you don't do anything crazy nothing seems to go really wrong.
