Wouldn't the job of handling discipline fall to the staff, and the heads of the Houses specifically, not Dumbledore? Also, I think it is less likely that there are no consequences for misbehavior, and more that we just don't see them, as they aren't usually relevant to the plot. For example, the mirror Sirius gave Harry was originally made so that Sirius and James could communicate with each other when they were is separate detentions. That probably means that happened rather frequently. The Twins are occasionally mentioned as having served quite a few detentions as well, but we only ever really hear about it when Molly is yelling at them for it (and comparing them to Percy, earlier on.)
The wiki actually has an article on this subject, and it doesn't look like the situation is quite as bad as you make it out to be. For example, Neville was banned from going to Hogsmeade for the rest of the year in book three, for writing down the passwords to the Tower, and leaving them where they could be stolen. I think that is a bit more than a minor, temporary inconvenience, as is banning Quidditch players from playing.
Also, do we ever actually see Snape bully any students other than Harry and Neville?
