The fact is that money makes "the world" - including Walt Disney World - go 'round. If WDW doesn't have the money, they need to make the most of what they have. Whether we want to admit it or not, I'm sure that Disney is suffering somewhat in this economy like everyone else. Therefore, they have to find ways to cut corners.
They may have to close less visited attractions (COP, Timekeeper) and only open then and have someone manning them (and pay them) when they will have more attendees. They may have to choose opening areas of the park after the rest of the park opens (e.g. Adventureland). I'm sure they looked at the numbers and saw that there were not many people riding the attractions in this land when the park first opens. Admit it - you run to Space Mountain or Splash Mountain or somewhere in Fantasyland when you first arrive at MK. Adventureland probably got hardly any visitors until 10 am anyway. Now you don't have dozens of people sitting around getting paid for doing nothing because no one is there to demand it.
They may also have to change the way they do maintenance. Daytime crews to maintain the parks (painters, etc) are cheaper than nightime crews. Have you ever called a plumber at night or on the weekend and compared that to daytime hours during the week?
If you have fewer cleaners that come out while guests are still there instead of waiting until the park closes, they will be off the clock sooner and therefore cost less.
This is what it boils down to. WDW's philosophy has always been to provide magic to the masses. I don't think that has changed. They may have had to change the amount of that magic and the way they provide it due to limited resources but I honestly believe that if we are patient, WDW will return to their earlier practices of painting and cleaning during the night and having an army of sweepers to clean up after you before you make a mess. In the meantime, find the good (and great) in what WDW has to offer and enjoy it.
