An example of this I've personally seen is a friend who works on COBOL mainframes at a bank.
He writes COBOL and maintains a banking system that keeps the world running. Literally like a billion people die if the system he maintains fails. I maintain a VC funded webpage that only works half the time. I make more than him, a lot more.
You should ask your friend what they do with all of the half cents that are floating around in the banking system.

This has to be an exaggeration.
I can personally attest that I'll die if my bank's COBOL mainframe fails. Really got a lot riding on this.
If the banking system failed? Would be pretty bad...
