Stoned like a quaker witch

I really like to make music and cool metaphors, that's where the title comes from. Anyway, I have a very interesting graph that I would really like to see. This graph would gather lists of all the most important career jobs in the united states by number. For example, in the year 2009 there were x amount of firefighters, y amount of doctors, and z amount of attorneys in the most recent us recession period. Then a different spot on the graph compare to how in 1932 there were x amount of firefighters, y amount of doctors, and z amount of attorneys during the great depression. Not only would it show firefighters, doctors, and lawyers, but all common jobs like food distributors, drink vendors, ect. This would come in handy for people who like to see where they stand in their current carreer as opposed to its standing years or decades earlier
