I can see the rationale behind class skills.
There is nothing preventing your fighter from say, learning how to play the violin (eg: ranks in perform), since 3.5 did away with exclusive skills. However, this does not mean that it will be easy for him to do so. For instance, there may not be any music tutors in the fighter academy, so he may have to resort to learning by himself from scratch. Compare this to a bard from a music academy, who has access to all the resources he needs to learn how to play music, and you can easily understand how the bard can learn to play the violin much better, and with just a fraction of the time and effort it takes the fighter to master.
Conversely, the fighter would have no problems perfecting his athletic skills, since the fighter boot camp will likely have access to all the necessary facilities for him to train extensively in these areas.
Likewise, I don't see how a barbarian living in the wilderness would have the same ranks in spellcraft or arcana knowledge as a bookish wizard.
Let's just say I am opposed to giving classes free reign over what class skills they can access.
