Oh, there's plenty of shitty craft beer out there. And there's plenty of expensive craft beer that is not nearly as good as some less expensive ones
Yes, but some of what is considered to the best craft beer in the world is very reasonably priced (RE: Heady Topper, Pliny The Elder, Zombie Dust, Founders Breakfast Stout, etc.). Can the same be said for wine?
Also, more expensive beers are usually justified in their cost because of the extra time and effort required to execute the style (e.g. barrel-aged beers or sours). You may see someone charging $25 for 750ml for a bomber of a an imported lambic, but you'll get scoffed at for trying to charge that much for an IPA. As a whole, I find beer to be very appropriately priced. Of course, there are some aberrations.
