Nope, not low at all. In the Midwest that’s exceedingly normal, even for non-entry level. $70k a year is living good in the Midwest, especially if dual income household ($140k a year is plenty when a decent house goes for $300k).

I think they're generalizing beyond software engineers with what they're saying. G&A, Marketing, etc roles pay significantly less than software engineers and that $55-75k figure is realistic in lower cost of living areas. Even in Colorado, which the Denver Metro Area is HCOL, there are companies (smaller, regional, not national/global) still offering that level of salary.
