It’s no secret that Malaysia plays host to a lot of foreign labour; a lot of cheap foreign labour. Among the criticisms of this happenstance is that it takes away jobs from locals, reduces the wages locals can command, and stunts productivity growth.
Underlying these concerns is a false view of the economy, that labour competition between foreigners and locals are a zero-sum game. The first concern isn’t true – given our ridiculously low unemployment rate, there’s not a lot of evidence that foreigners have taken jobs away from locals. Culling foreign labour from Malaysia would only reduce output, and remove industries that would only exist (or exist as cheaply) from the availability of that foreign labour.
