I would be much more frustrated if they became cheaper and reduced the quality of the product.
Whenever I meet one of these people, I ask if they are willing to negotiate a wage reduction with his HR. My logic is simple. If you think it is wrong for a business to sell a product at the maximum price they can demonstrably get away with like Lego does, then why is it right for you, a professional worker selling your labor, to sell your labor at a price higher than what is necessary for subsistence?
