"The first generation gets along well with the weapons and equipment brought with them from Earth. They maintain the old ways. The second generation follows along but already ammunition for the weapons runs short, the machinery imported from Earth needs parts. There is no local economy that can provide such things. The third generation begins to think of Earth as a legend and the methods necessary to survive on the new planet conflict with those the first settlers imported. By the fourth generation, Earth is no longer a legend but a fable ..."
"But the books, the tapes, the films ..." Roberts injected.
"Go with the guns, the vehicles and the other things brought from Earth. On a new planet there is no leisure class among the colonists. Each works hard if the group is to survive. There is no time to write new books, nor to copy the old, and the second and especially the third generation are impatient of the time needed to learn to read, time that should be spent in the fields or at the chase. The youth of an industrial culture can spend twenty years and more achieving a basic education before assuming adult responsibilities but no pioneer society can afford to allow its offspring to so waste its time."
Natt Roberts was being stubborn. "But still, a few would carry the torch of knowledge."
Plekhanov nodded ponderously. "For a while. But then comes the reaction against these nonconformists, these crackpots who, by spending time at books, fail to carry their share of the load. One day they wake up to find themselves expelled from the group--if not knocked over the head."
Joe Chessman had been following Plekhanov's argument. He said dourly, "But finally the group conquers its environment to the point where a minimum of leisure is available again. Not for everybody, of course."
Amschel Mayer bounced back into the discussion. "Enter the priest, enter the war lord. Enter the smart operator who talks or fights himself into a position where he's free from drudgery."
Joe Chessman said reasonably, "If you don't have the man with leisure, society stagnates. Somebody has to have time off for thinking, if the whole group is to advance."
"Admittedly!" Mayer agreed. "I'd be the last to contend that an upper class is necessarily parasitic."
