I am trying to understand the logic of paying so much and getting so little back
I'm not sure if too many on here would admit to being totally logical when it comes to all things Disney!

However, there is a logic behind buying into DVC as long as you know what you're getting. As many others have said, it's a one-time buy-in (unless you decide to purchase more points later on), and essentially what you're doing is prepaying your accomodation expenses up front for the next 49 years (if you buy into Saratoga Springs--the other resorts' points will expire sooner). The accomodations we're talking about are deluxe: studios, 1BRs, 2BRs, and at some resorts, a 3BR grand villa. If you enjoy staying at economy or moderate hotels just as much as a deluxe, then DVC might not right for you.
Another thing to consider is how often you plan to visit WDW or their partner collections of resorts that are available to DVC members worldwide--if you only vacation rarely, then again DVC is likely not a good choice. On the other hand, if you plan to travel to WDW every year or two for the next few decades, then you'll come out ahead.
Finally, two smaller points to consider. First, do not consider DVC to be an investment. Though it is currently possible to resell DVC contracts and possibly make a profit, there is no guarantee of doing so in the future. Second, one poster mentioned banking and borrowing. What makes DVC attractive to many is that you can bank points from one year to the next or borrow from one year ahead to the current year. In other words, if you had a 150-pt contract and you couldn't or didn't want to travel on vacation in 2006, you could bank all those point to 2007 for a total of 300 points. Or, if you wanted to stay in a 2BR villa at a peak season in 2006, you could borrow as many of your 2007 points as needed to add to your '06 points. In fact, you can bank, borrow, and use current year points all in one year; e.g., you wanted a grand villa in 2007--you could bank '06 points, borrow, '08 points, and use '07 points all at one time. Such a concept makes DVC a very flexible option.
Only you can decide if buying into DVC makes sense for your particular situation. Many feel it's not a cost effective means to enjoying WDW. Others feel it is the best deal going. There are plenty of links--including some FAQs on the main DIS page--to find out more about DVC membership. Good luck in your decision.
