This seems to be one of the biggest misconceptions about dues. In fact, if you follow the link in the original post you will see comments about how DVC is trying to make the dues the same at all resorts.
Just so it does not derail this thread further. Dues cover the actual costs of running the resort, plus a portion set aside for capital improvements. Capital improvements mean, if they estimate it costs $1M to pave the parking lots, and the pavement lasts 10 years, they will collect $100K each year to hold in reserve for that re-paving project.
Dues, by Florida law, cannot be more or less than the cost to run the resort. Profits (from DVC, or from the parks in general) cannot be used to offset the dues, and dues cannot be more than the cost to run the resort.
Now, DVC could do something wacky, like call housekeeping a perk, and then we would not pay for it in our dues, but that would have a hard time passing an audit.
So, if your dues are too high for your liking, you can complain that DVC is spending too much to run your resort. Maybe you want to get rid of those CMs that do the poolside activities, or perhaps scale back on the plantings, or the outside movies. You can complain that the resort is being run inefficiently and wasting money, but none of that money goes to DVC.
Of course there is the possibility that Disney as a whole could be using DVC as a dumping ground. Such as charging them 500 hours a week for pest control, when pest control only spends 100 hours a week on DVC properties. Thus shifting the cost from WDW to DVC members dues. However that is why there is an independent auditor - usually one of the big four.
