This interactive map shows average commute times according to the US Census Bureau. As you'll see, few areas have times over 35 minutes. They are mostly distant exurbs of expensive big cities, where people have to drive or ride transit for long distances to get to & from work.
I just looked up the reported time for my home. At 22.3 minutes, it's just a hair less than the 25 minutes it takes me to drive to the office. Lucky me, I only go in once a week or so!
You're right that some unhappy Americans do commute more than an hour each way. I had a friend who drove an hour and ten minutes from our little town to his office in Columbus, Ohio. No thanks!
