The economy won't support that many Walmart Tire Centers either. That was just an example. My point was that there are paths from these "crap jobs" to "real career" and traveling said paths require about the same level of "how do I tee up my next move for more money" long term thinking as being a successful camgirl.
You float the idea of perpetual growth in any other context, and you'd be called a fool, but apparently the economy doesn't obey the same rules of common sense.
