I was chatting just now with my dad (age 66) about discriminatory pricing, and he remarked that senior discounts are anomalous: why should a class with more than average wealth *and* leisure need extra tempting to go to the movies? He suggested cultural lag: once upon a time the elderly were poorer than average, and nobody wants to be the first to stop giving them a break.
