re: "Freelancers in different geographic locations command different rates. Freelancers... compare their pay rate to Freelancers in the US, and want to get paid the same. This, of course, defeats the very purpose of Upwork... If you make the pay rate of all within the same company public, that reduces the value of Upwork."
re: "Rates should be based on freelancers experience and skills but not on their location."
These statements, from two different Upwork users, are both true.
