LOL! In looking at that survey its the guys who went to HS, got out and jumped into IT, got years of experience under their belt, got that one cert that is required to get past HR and kept working at their specialty. They're making the 83-85k.
Meanwhile the guys who went to community college or got a BS then got out and collected certs get paid 80k.
Sure the guys who went to grad school and then went cert crazy make 86k-90, but they had to pay off big school loans and study like crazy!
