In her "Keep Austin Employed" letter ["Postmarks," Aug. 1], Caroline Kittelson complains that she was forced from the weird side to the dark side by employment pressures. I welcome her to the real world and point out that employment pressures result from ecological pressures, which in turn result from population pressures. Freedom to be weird (or anything else, for that matter) requires elbow room. As the human population grows beyond optimum density to maximum density (in about 40 years, by current estimates), freedom diminishes from maximum possible to zero. "Smart Growth" is not dead, it's just an oxymoron until we contrive a means to defeat the beast of armageddon (i.e., the global population-explosion) with its Four Horsemen: Famine, Plague, War, and Avarice (the first two being nature's responses to overpopulation, the last two being man's best efforts, to date).
