A great many lefties are positively economic-wise anti-growth. That is one large reason why they hate capitalism. Capitalism and free-markets mean growth. If everyone who wants a job has one, then what would they need lefties for? That is why lefties hate capitalism. Since lefties are for more control over peoples lives, ergo they are for more government.
You do have a point - I remember university leftists tend to be extremely post-modern and anti-economic growth types. Rosseau's noble savage seem to be the goal they are striving for.
In fact using this lens as a reference the Clintons and John Kerry and Co are remarkably right-wing. Rush Limbaugh? He could well have come from another planet. (Mars vs Venus) The type of academic leftism never gets enough votes in real-life - I suspect for leftists active in politics, even the true red ones like Dennis Kucinich, either know the noble savage idea is BS, or he well knowes this won't get him elected so he hides thsi real thing behind the "moderate" posteurings.
