It really depends. Suggesting that topics like accounting and finance can be picked "up in a night course" is a bit like saying programming... I know that involves some Javascript and CSS, and couldn't you just pick that up? I have no formal programming education but started coding 35 years ago. I also have an MBA in finance. For my brain, learning something like functional monadic composition is something I was able to do on my own, but there is no way I'd ever have learned finance at that same level on my own. It is worth noting that there is a pretty big difference between an MBA in finance, marketing, or operations/supply-chain. As different as developer, tester, and devops at least.
