"Because they can" is the short answer. As long as there are no direct personal consequences from type of needless waste, a large segment of the population will just keep on doing it. They'll be dead long before the consequences hit, after all. Edit: However, it should be noted that the confetti is made from waste paper and is biodegradable. I still think it could be put to a better use, but it's not like they're dumping a load of plastic on the streets. That still leaves 57 tons of trash that isn't recycled, though. What a waste.
