"You have to understand that when you complain about something to a business in the US, they fix it, no questions asked, that doesn't happen anyplace else"

I was told that by the Director of a Pakistani mobile telephone company that had worked for years at Sprint in Kansas City but I've heard it a dozen times from people around the world.  The US has the most competitive private sector with the most demanding customers who in general get the very best price, service and value available in the world today.  We trash our governments incessantly for good reason but compared to most of the world they are remarkably responsive.  Things just work.

Which is the argument Virginia Postrel makes here in much more eloquent detail than I can.  She argues "Two Cheers" for first world problems, because without demanding consumers we wouldn't get innovations that we all count on.

Rising expectations aren’t a sign of immature “entitlement.” They’re a sign of progress -- and the wellspring of future advances. The same ridiculous discontent that says Starbucks ought to offer vegan pumpkin lattes created Starbucks in the first place. Two centuries of refusing to be satisfied produced the long series of innovations that turned hunger from a near-universal human condition into a “third world problem.Read the whole thing.

So go ahead: bitch about that product, service or price, you're helping civilization advance.  But do it like my momma:  with a smile and exquisite courtesy - that way it really burns.
