Similar wages, because the overseas senior talent wont work for anyone's corp for dimes, in contrast to what some seem to think. They have their own career trajectories, their expectations. If you don't pay them more than what the local corps pay, you wont get them because those local corps come with a lot of perks and the social status. The latter can be quite more important in many regions of the world in respect to the expectations of your family, relatives and friends so the pay difference must be worth losing it.
