So no more youth ticket prices, senior discounts, etc.? Price discrimination is a very commonly-used tactic, and it goes by many different names.
France grants free museum admission to adults under 26, which strikes me as a better policy than charging the highest price to access cultural works to the people who (a) have the least earned wealth, (b) the least lifetime exposure to those things.
Same applies for theme parks, where the target audience is young adults and families with small kids.
I'm not defending any of this — just pointing out that price discrimination is sometimes about ATP, and sometimes about WTP.
"Seniors pay 20% less for movie tickets at Tuesday at 1 pm" sells tickets that few people with jobs would buy, regardless of price.
