Robert:

Without constant effort and exertion of local energy, the local neighborhood runs downhill.

If that isn't true, then do some believe that : Without constant effort and exertion of local energy, the local neighborhood runs uphill on its own?

I can live with some believing that.  In fact, I do.

Some cavemen did strive, and did run uphills.  Not all of them.  And not all of them did survive. 

Those that did eventually made it trivial for any idiot to survive and even, to vote, to the point where today, our elite are handing out Nobel Prizes to a Paul Krugman; now thankfully booted out of Princeton.

There might be some faint glimmer of hope for Disneyland...
