I think, perhaps, a large part of the issue is equating the notion of "balance" with "balance of power in battle". While that is part of balance, I don't think it's the only consideration.
I think that classes are balanced if they are found to be equally effective over the course of the whole campaign. Not just the battles, but the whole story. Even in a dungeon-crawling, hack and slashing campaign, there's more to playing than the fights.
It's been mentioned that part of the issue is that some players aren't as skilled at utilizing the full potential of some classes. This is true. However, it's also true that some DMs don't provide the avenues for proper use...
Yes, in dungeon fights, the fighter, cleric, and wizard are all tops in combat. But what about the Baron's Tea Party? Has that combat cleric even bothered to take any diplomacy skill? And, does the DM play up the fact that going into the wilderness in a fantasy world is pretty hazardous business, where knowing what you're doing is important? If the DM focuses on combat, that will skew perceptions.
