Yup. The only alternative is what countries are trying right now, protectionist controls on immigration and tariffs to prevent companies from manufacturing elsewhere, or laws that require attempting to locally hire before hiring on visa (hilariously easy to circumvent). But that's in opposition to capitalism, which many big fans of that mode of production will quickly remind us. No regulation! Pure capitalism! Can't have your cake and also eat it. This trend is one excellent example of the inherent, unsolvable issues with capitalism.
