Every Indian I've ever met has been a medical doctor, every Filipino has been a Toshiba repair technician, every Vietnamese I have met has been a medical receptionist, and I have never met any of the other nationalities I assume they don't exist.
But on the note of Indians making the most it's not unreasonable to understand, because most I've ever seen are in high paying jobs or gas station.
I live in the South the only region that matters.
