It's interesting to see the evolution and battle between secretary and truck drivers. Some other notes: DC went from Janitor to Lawyer which is hilarious, and farmer has largely disappeared. I wonder if it's because of agricultural developments and larger farms buying out smaller ones or what's going on there.
I really want to take a look at my major/future profession and see how those job numbers have changed over the years.
Here in Nebraska, we talk about 80's, or plots of land that are eighty acres. My grandpa owns quite a few, and he leases a pretty large portion of them. Farms are definitely way bigger than they used to be.
