I wasn't implying you were talking about defense, I was just saying that if you're only about money then you can make a lot of it developing weapons for the government.
Different universities specialize in different things. I went to an engineering university that issued mostly engineering degrees, plus a few business degrees. Both of my state's public universities also have fairly large colleges of engineering with quite a few engineering programs run by them. You're also not only competing locally, but with remote, outsource and H1B visa workers. There is plenty of supply.
God forbid you have to train an employee in the specialization you're looking for once in a while.
That's news to me
