> Plenty
Plenty of tech folks make north of six-figures and often do better than most, but neurosurgeons make $800k, and plenty of mid-level medical types can pull $300K+. I personally know a dentist making "in the ballpark of 400" (his words) in the Washington DC 'burbs.
There are certainly IT/CS gigs paying north of $600K -- they're discussed all the time here on HN -- but those don't really exist outside of SV and maybe a handful of other areas, and generally require a pedigree that, while not a Med School, are still fairly non-trivial.
Your ITT-Tech trained Active Directory Admin isn't going to make anything near GP or Dermatologist money -- most tech, even with real degrees and certs, wont.
