I never for a minute meant to imply that Roy wasn't a very strong and efficient partner to Walt. But, it isn't possible to think that Walt wasn't willing to hear Roy out, with the exception of a couple of situations. It was indeed Roy that found the way to pay things off and keep a strong vigilance on the company finances. However, without Walt's determination to make thing happen Roy wouldn't have been needed. As it was, he was very much needed.
Without Roy though, there would be no Walt Disney World. Cows would be back in the pasture. Walt Disney World, as it stands now was not even close to what Walt had envisioned with the exception of Magic Kingdom. At least not much that had been made public. Walt wanted his own controlled city. MK was to draw people in a help pay for a large part of it. In reality the statue in Magic Kingdom should be Mickey holding Roy's hand.
