I think us IT'ers feel somewhat buffered in life just by the fact that it's quite possible to get job offers with $600k salaries...
I'm sure I'm less intelligent than the average HN commenter and I'm certain there are many here with greater infosec expertise. So what explains the salary package? It's the combination of skills in this case. People are usually either good technically or good at sales. Rarely they're good at both. That's why most technology companies sales organisations pairs up an account managers with a tech guy. My talent was not being the best at either, but being uniquely good at both.
