I feel like they can easily make the stuff you get from these things at least marginally worth it and still make a ton of money. It'd at least make the adults feel a bit better, but somehow it always seems to be the first thing they try to save on.
Then again, I find that I'm often the only one that has issues exchanging $20 for fifteen minutes of fun and a $0.1 toy.
You can never make enough money. Most local governments don't care that kiddy games are unregulated and you have no shot at winning the grand prize. Hence, "It was the perfect encapsulation of modern American capitalism."
