That last part I can agree on: I teach at a private school, and the amount of input from parents that occurs today is unprecedented, according to the older teachers I work with. Parents being involved is typically a good thing, but parents sending emails asking for better grades for their child? Not so great. It's not everybody, certainly, but among the set of people with enough disposable income to be guests at Disney resorts there does seem to be a slight trend that way. I can't 100% blame them given how high tuitions are at private schools and at public and private universities, but it often does more harm than good for the kid.
The trophy thing never much bothered me in isolation, though; kids should have a way to play that doesn't involve a message of "you are constantly in competition with everyone around you!". It's when it bleeds into a mentality of not letting your kids fail and learn from mistakes, or not letting your kids fight their own battles sometimes, or not letting your kid have a measure of freedom to explore boundaries (within reason) that things turn sour.
