Okay, to clarify it for you...
"Work" is not simply spending eight hours a day doing a simple task. Maybe a more accurate term might be "accomplishments."
Only the dimmest bulb looks at a guy behind a desk at a computer terminal and a guy on an assembly line welding a car body, and assumes that only the latter is doing "work," or that somehow the level of pay should be related to actual physical effort.
Do you have any idea what proportion of our economic growth is probably directly related to what Bill Gates and his people created?
