The counterculture light was so bright it began to attract moths (people who sadly were not intellectually or spiritually prepared to meaningfully assimilate transformative multi-dimensional data streams from hyperspace) and stinging stink bugs (the thugs that invariably invade every utopia) in such great numbers that they eventually crowded out the butterflies (the educated middle class truth-seekers who switched on the light in the first place). That's an oversimplification, of course, but it's good to bear in mind that like it or not, enlightenment has always been, even in a golden age, pretty much limited to an elite. In America, the relatively finite psychedelic culture was shoved aside by the burgeoning boogie culture, whose drugs of choice were booze, speed, and cocaine; and whose goal was not to attain spiritual bliss, deeper understanding, or an end to war and repression but rather to get thoroughly fucked up.
