I've never believed Apple (or some/all retailers) are there to "milk the employee for everything their worth." But you do have to consider the math: Apple employees more than 65,000 in their retail stores globally. If each were given some kind of $1000 yearly increase (wage, benefits, bonus, etc.), that would amount to $65,000,000 extra PER YEAR in retail employee compensation. I'm not saying the employees do not deserve it, but $65 million extra per year on a simple $1000 per employee increase is a LOT of money. I would argue that each retail employee in the USA would (as would we all) ask for more than a $1000 YEARLY increase. So keep doing the math and see how the numbers roll out into the hundreds of millions or even billions.
Apple retail employees earn between $17 and $30 PER HOUR selling 3 products (iPad, iPhone, Mac). If I were 20-30 years old, I would kill to earn that kind of HOURLY WAGE (hourly wage isn't (and shouldn't be) a CAREER folks) and work at a super clean, super fun, super friendly retail environment with cool perks like deeply discounted hardware (if not free). Compare working at an Apple retail store to your local supermarket or clothing store or any old store in a mall or the lawn care place in town or being a waiter or pumping gas or working at a car wash or working at a fast food place or <insert your favorite hourly wage job here> and I'd bet you'd pick Apple hands down.
Lastly, the last time I checked, hourly employees do not get a "share" of what the company makes. You want a stake/share in the company?...go work in corporate and work your way up to some kind of Director or VP or Executive level role where the DECISIONS YOU MAKE affect hundreds of thousands of jobs as well as tens or hundreds of millions of paying customers. Until then, you're decision to suggest the 128GB model over the 64GB model for 9 customers a day pales and frankly, has no market driver.
