I agree 100% with this. I was being berated earlier for suggesting that the point of WDW was to make money. In fact the response of one poster was an emphatic "No".
.....and for the record, the sky is grey here right now.

Just kidding.
Its actually grey here too.
But what I'm saying is there's a fundamental disconnect. The "No" wasn't literal, meaning that the company didn't need to make money. We all know it does.
The "No" is directed at the overriding philosophy. Not to oversimplify again, but it boils down to which of these we think is best for Disney:
1. Wake up in the morning and ask "How can I make money today?"
2. Wake up in the morning and ask "How can I entertain people today?"
Or maybe you look at it as a question of what comes first. Do I come up with new ways to entertain and then decide if they will make money, or do I come up with ways to make money and then see if they will entertain?
When points that are critical of Disney are countered with "it needs to make money", it sounds like the person is supporting the former in both of those examples.
That's what the "No" was directed at. Not the idea that a company has to make money, but what is the best way to make money from artistic endeavors. You mentioned that it has to get a return from its investments, but nobody is saying otherwise. Its just a question of what it invests in, and how it does it.
We kind of have to assume that we all know that in the end, money has to be made.
