I once applied for a "database admin" job at one of the big credit card companies. The job description was basically "run all our Oracle databases" and the salary was in the mid 2 millions USD, but I assumed that figure was typo'ed or something ( an extra 0 maybe?)

In the interview I learned that there was no typo and it was to be one of the seven people on the planet that run the databases for this credit card processor. They said "if the database goes down then we are losing billions of dollars a minute".

Anyways I didn't get the job, but they're not all underpaid.
