You have the mentality of a peasant. Whatever the nobles do, it must be OK because they would never take advantage of their position at your expense. They're so much more deserving then you.
Let's use a car analogy: suppose that you buy gas at the same station that Google execs do. They get charged the rate that the gas costs at the refinery, and you pay retail. Their gas is 25% cheaper (made up value) then yours. You have to pay for shipping costs, infrastructure costs for the service station (electricity, upkeep), the salaries of everyone involved between the refinery and the pump, etc. All that stuff has to be paid for to get the gas to the pump, so you are subsidizing their gas.
Except it's not a private company selling the gas, it's government services paid for by your taxes.
+5 Insightful? I could see +5 Vituperative, but your post lacks both insight and manners. Rather than calling him a peasant, why didn't you spend time reading the linked letter and article widely cited above? NASA says, for example, "While we concluded that the fuel arrangement between Ames and H211 did not result in an economic loss to NASA or DLA-Energy..." The cost H211 paid was the fully loaded cost. Go look that up in an management accounting text. There were no government services paid for by anyone's taxes. The price they paid was below market rates -- at the time the deal was signed all fuel was provided by DoD and sold at subsidized price (DoD craft) or fully loaded cost (non-DoD craft, including the H211 craft that NASA sometimes used). Here's a flash for you: sometimes these craft just flew in the air, so they didn't have the option of going to another "gas station" down the road -- Moffet Field was the only game in town for NASA, and was often convenient for H211 folks. Cost recovery is the default option for charges at most airports, and managers are very good at calculating fully loaded costs.
The problem is that H211 was getting a better deal than other craft at other airports in the area, not that the government or taxpayer was losing money. Given how much NASA was saving by having easy access to H211's aircraft, everyone was winning. However, NASA decided it looked bad, so to avoid any allegations of impropriety (like yours), it was in the government's interest to collect market rates and pass the profit on to the Treasury, so they've been doing that since September 2013. Mr. Schmidt's compensation is irrelevant.
