While I don't necessarily like to see people brag about working hard, I definitely agree that this post is one sided and misses the point. If your work is just a way to make money and do things you enjoy, you should change your profession to something you're passionate about. Your work should be your craft. But if you'd like to just make money and explore the world and try different hobbies, more power to you. But don't assume that everyone who works long hours is just inefficient.
And I also think the comment about the truck driver is extremely snobby. Truck drivers provide an essential service and they have to work long hard hours away from their families. I don't care if you make twice as much and work half the hours. Don't be a dick.
