Fully 98% of employed Americans making over $75,000 a year are satisfied with their jobs, significantly more than any other income group. Fully 38% of those in the highest earning bracket say they are completely satisfied with their jobs, and 61% say they are mostly satisfied. That compares with just 31% of those earning less than $30,000 per year who are completely satisfied, and 57% who are mostly satisfied, according to Pew Internet Project.
