How exactly is it "abuse" to be paid a wage that is highly competitive with the other options in your given location and standard of living? Did you even read the comments from other Kenyans in this discussion? Your language is hyperbolic and ridiculous.

Over time this lifts those economies up which then forces their pay to go up; it's like slow arbitrage over time. But as it's happening, yes, the paying companies get a better deal. Temporarily. And that is fine.
