It's basic economics: wages are low because cheaper labor is available.
For instance, if working on an Alaskan fishing boat pays $2,000 a week, you might take the job despite harsh conditions. At $200 a week? Unlikely. But for someone from a less-developed country, $200 might feel like $2,000.
Remove the supply of lower-cost workers, and the resulting labor shortage drives wages up, seeking equilibrium in the market.
