Sorry yanks, you're out to lunch on this one. If you don't like MWR, don't join worlds that have them. Building a "dynasty" by losing is the easiest strategy in this game. That's why over time, many worlds have enacted MWR. That's also why, over time, worlds that have teams winning 40 games for 3 seasons and later becoming dominant are now considered "'tard worlds". Worlds have added MWR because it has an overall net positive effect. Everybody wants to win for 10 seasons. Not everyone can do it. There are many strategies not even addressed here (see the "Tanking 101" thread).
The bottom line is that a good owner can turn around a franchise, sometimes very quickly, even with good competition (I do know this first hand). Teams win WS with 80 wins. I've seen it happen. The idea that owners want to be sure they can win 108 before even calling up guys from AAA who are better than their MLB players is what decreases the enjoyment level in a world. No one is saying you shouldn't use the arbitration system to your advantage, or that you should rush every prospect before they're ready. But if you're transferring 40M (+20 to the Prospects Budget) every season and hanging with a 40M or less payroll, you are tanking, pure and simple. Can you get away with that in a MWR world? Sure, but not for long. Nor should you. What HBD doesn't have is the natural feedback of fan support and profits (or lack thereof). There are no consequences to it, which is why it works. Worlds that have MWR have put in a process, an imperfect one, but a process that encourages competition. It's better than the alternative, and the worlds that have them, by and large, are far more healthy than those that don't.
Again, if you don't like MWR, don't join a world that has them. If your world adopts them, you can always go somewhere else....
