If nobody bought Taco Bell beef or Chicken McNuggets, could you imagine what steak would cost? If everybody had an advanced degree, what would one be worth? And what would less-demanding labor cost?
No one compels anyone to buy tickets for Justin Bieber or Miley Cyrus, low-grade horror movies, 'rasslin' shows, Transformers, or Twilight. No one is forced to watch the Kardashians or Honey Boo Boo or Dance Mom or Bristol Palin. So far as I am aware, every McNugget, Wendy's Triple Baconator, cigarette, and 64-ounced watered-down fountain soda is consumed voluntarily. These pains are self-inflicted (although the purveyors of substandard products have nothing about which to feel proud or morally adequate).
Children deserve better. Adults deserve an opportunity to be educated. Beyond that, it's a free country, more or less.
