yeah but apple isn't a charity or government. they aren't in the industry of solving income inequality. imagine if you went to a restaurant and they checked your income and set the price of your meal based on that. it doesn't make any sense.
Completely OT, but, if you file a Schedule C and are deducting 50% of the cost as a business expense, then effectively the meal actually costs less the higher your tax rate. In CA and at the highest marginal rates the state+federal deduction is worth around 20% the cost of the meal!
