Let's say someone who earns $50,000 a year uses Office for 5 hours a day while making a living. It's also a purchased copy so it lasts at least 6 years. What's that worth?

How does it compare with the cost of, say, one Starbucks a day?

If you employ somebody on that salary for 6 years (so add extra employment costs including taxes, insurance, office space and perks), what percentage do you save by not paying Office's shitty price?
