While raises are pretty much always good, and I do think Apple employees could use a bit of a raise, there are a few points I'd like to share here...
The opinion that Apple should provide raises simply because they are very profitable is to me, not a good reason. It does demonstrate, however, that they are CAPABLE of providing a raise (since they are not poor), and that should influence (positively) the probability of providing a raise in conjunction with other factors, but it should not be reason alone just to provide a raise.
That being said, I do feel Apple employees should get raises, reasonable ones. And there 2 main things I want to say about that: 1) Working in retail is HARD, and anybody who has done this KNOWS this, assuming that the person working is actually trying to be good at their job. You have no idea how ridiculously rude and horrible people can be until you've done a solid stint in retail. It's one of the most stressful aspects of this type of work. For full disclosure, I USED to work in Apple retail (for a couple of years) and I've also worked in other electronics and computer retail environments (including Futureshop and Best Buy). And also, for full disclosure, before some of you say I'm just a retail worker no "better" than a burger-flipper, I've also worked what some of you might call a "real job"; I have a Master's degree in science an I've supervised research laboratories, and I have senior experience in other environments as well. My point is simply that working in retail is substantially harder than many people realize (especially in a place like Apple where (if you're a GOOD employee) you have to know a lot of complex knowledge, and don't forget how ridiculously busy those stores are!).
2) Not everyone in Apple is just a salesperson. And don't forget that in a lot of sales roles, employees get compensated by commissions. Apple doesn't. And they shouldn't, at least not directly (I don't like the commission model, as it produces a conflict between the goals of the salesperson and the goals of the customer (it doesn't in truly honest commissioned salespeople (and they do exist) but it definitely makes for a crappier shopping experience, in general). But there are MANY other roles in the Apple store, and they are difficult (I've tried a few of them). They are also rewarding positions, but none of them are easy. You have different grades of technicians (ones for iOS devices, and senior ones that are geniuses for computers). And in general, these technicians are very knowledgable. Yes you have some bad apples, and I can't speak for every store (maybe you have a bad one), but every store I've been to and worked at had extremely knowledgeable geniuses and iOS technicians (mostly

). And then there's the Creatives (the trainers and educators). They were also a very very knowledgable group (and more consistently so than the geniuses, dare I say). And finally there are other people behind the scenes that you don't see as much, such as the back of house team, and they work very very hard, believe me.
And , in terms of personality, hard working attitudes, ETHICS, and knowledge, the team at Apple is mostly great, especially when I compare it to any other electronics and computer retail environment I've worked at. I've worked in big commission based stores, and there are definitely some honest folks there, but for the most part, those types of sales-people are light-years behind the type of people at apple, I really mean it. No offence! And there are reasons for this, including Apple attitude in the retail business and their hiring practices and methods. Are Apple stores perfect? Of course not. Humans are not perfect. There's always the unscrupulous or just plain crappy employee. There's always a bad store. But are they WAY better than any other technology retailer's environment? Hells yeah.
And so, I do believe they deserve raises in some reasonable fashion. From what I know, most of them are not getting big raises (e.g. the up to 25%), most raises are just a dollar or two max.
But while I believe they do deserve raises (as do people in many other industries), they do not deserve this simply because Apple is successful and makes a ton of money. They deserve it because they are (mostly) a talented and capable and hard-working and ethical team.
That's my 3 cents.
