Most doctors, teachers, lawyer, plumbers do not create "other jobs" any differently than any other position in the economy. A drug dealer probably creates more jobs than a doctor or lawyer because the drug dealer serves as a retail distributor with a supply chain behind him or her.
I think there is a difference between "affecting" jobs and "creating" jobs.
In no particular order, as said to me by an electronics/english instructor: These basic industries are crucial for they create other jobs.
I have a lot of fun listening to the initiatatives that our leaders introduce and champion. Bill Clinton, in the 90's, was in the sweet spot for us Boomers, where we had to heavily use all forms of Industry. Now that our Boomer kids are now into their 20's, and we are approaching retirement, we can see what Industry will be used more heavily and some to lesser amounts. Something to think about in the next 6 months.
