That would surprise me. There may be enough people working for the big tech employers and financial industry in high cost of living areas in the US to be a mode. But the rest pretty much spans the gamut from entry level sys admin jobs in manufacturing and retail up through well-paying but not FAANG level development, architects, etc. throughout the US. Bio dale would imply you have well-paying jobs and poor-paying jobs with not much in between and nothing in my experience suggests that’s the case.
