You've got derailleur envy. I've had that before. The deore stuff will last a long time and will perform the same as anything above it. I have had XT, LX, Alivio, Acera, Tiagra, etc. and I can tell you that when shifting if you didn't look down, you would never be able to tell the difference.
The biggest factor is having evertything adjusted correctly. A properly tuned Alivio is much better than an improperly adjusted XTR. I do concur that the less expensive derailleurs wear out somewhat faster but even then, that is a long time for most riders. (plus they are cheap to begin with)
