In case you wanted a serious answer, the biggest similarities are by function pairs--ST, SF, NT, NF, although there are patterns within individual types as well.
ST: production management, physical science, engineering, emergency personnel, tax and other detailed law careers, small business owners--handling reality
SF: customer service, nursing, teaching (especially younger children)--any career where you're meeting the individual needs of people
NF: counseling, management consulting, communications, training and development, human resources, religious careers
NT: strategic planning, engineering, theoretical science, management, IT
These are just general patterns borne out by stats on thousands of people. And yes, there's been research on why Feeling types settle for lower pay...and anyone can do anything if they are motivated to master the content/skills and work with a lot of people who aren't a whole lot like them...
