Only in the minds of those who forget their science and history does Malthus and The Jetsons live simultaneously.
As I watched last week this moss-covered creature emerge from the lake fronting our 18th hole hauling two large nets filled with balls, it occurred to me that the price of new premium balls ($39.99/doz ProV1s and the like) might have some elasticity. If the price goes up, the salvage business grows and the environment is saved from careless golfers. I suppose that those of us who wish for a clean environment should be rooting for the rich guys to keep pushing up the price of new balls, and, as a result help clean up our bodies of water.
BTW, my limited knowledge of physics makes it hard to get my arms around a "positive ball". I am under the impression that the M in the equation has a little bit to do with the resulting E. So, ceteris paribus, is it possible for my sub-95 mph drive swing to hit a "positive ball" as far or farther than my son's 115+ mph? I just don't think that is what Napoleon Hill meant when he said "What the mind can conceive and believe, it can achieve".
