I really don't know much about economics, just barely the basics.
But I was a bit of a Sci Fi fan growing up, and they told me by now we'd be vacationing with the Jetsons on the moons of Jupiter.
No Capitalist is going to build glass freeways and leave vast swaths of greenery between their lovely skycrapers because they like wasting their money. Hell, those being born today are going to live in a pure Capitalist society to the max - Mad Max, that is - since the guzaline that fuels this society will be gone and the Ogalla Aquifer that waters most of of the planets crops will be dry and the few hundred people left over after the World Famine and Cannabalism Riots of 2062 will be in ye olde surival of the shittiest assholes mode, only without the cute cars and cool Punk accoutrements.
Anyone pretending to decry or is banking in Big Brother/Uncle Sam to get us out of that jam with some newfangled putty, elbow grease, and the latest in socialism projects to amend our shortsighted messes are in for a rude one, because such is dependent on contionous economic growth which has been faltering since the 1960s. No money means no goverment teat for even our illustrious trailer park denizens, so they'll be gone with a few tornados because DC is gone and the dumbasses in Tornado Alley and the Hurricane Zone still haven't figured out that replacing plywood with composite board still is not better than bricks in terms of weathering out those storms.
