This may be the best explanation I've seen yet for how things should be. Want to buy more ride tickets (or even FP's), face time with Mickey, or something else - that's perfectly fine. But you are still in the same queue or same dining room with everyone else, and nobody is made to feel like a second class guest just because they aren't spending as much.
It's all about choices, too. Essentially if you are staying on-property, entering the parks, and eating in WDW restaurants you are already spending enough money that you can pretty much do any activity or buy any premium package Disney may offer. Maybe the uber-rich buy premium everything while the rest of us decide which few specific item(s) we want to splurge on, but my point is (for but one example) any All-Star guest can indeed stay at the Grand Floridian. It might well mean a two-night stay instead of a week in the value resort, but if that's what you really want, you can do it.
