Aren't we missing the main topic of the POST ?
I think the main question here is about the "increase in rate" & whether it is same for all or is it selective of the freelancers?
It doesn't matter whether in some country people work for $20 a month or $20k a month or even $200k a month!! The fact to the matter is whether oDesk is providing the same platform to all oDesk freelancers or to a selective few only?
I think it is and would be a healthy conversation in its own merit if we discuss it to the point.
