This graph is based on the hours away from home for work so it really doesn't mean "harder working states". Terrible chart actually when you consider that MD only has the top spot because most of the people that live in MD have an unusual long commute in from work. So a long commute into work = a hard worker. Nice. Also, what happen to the saying work smarter not harder? Does it mean the top "hard working states" are full of dumb people who haven't found ways to minimize their man hours? I get farmers, there's not a way around the man hours there.
But please, don't tell me that Maryland is a hard working state just because so many of them
a) work in Baltimore but don't want to live in that crap town or
B) work in DC but don't want to live in that crap town
Typical for this board. Misguiding stats.
