Whenever someone goes out of their way to complain about the profit someone makes (as though its dirty somehow) I always wonder... have you ever calculated your own profit margin? Having a job is rarely free and, unless you you're just living off prior earnings/trust fund/etc. this is a figure you can come up with. Most people I've known, including myself over time (I've for worked everything from minimum wage to very healthy salaries), have done pretty well in the profit margin percentage area as compared to the 32.8% markup you cite.

To be fair, you certainly didn't register a complaint per se in your comment, but something to think about before making that complaint.
