You can. It is called outsourcing. Seen it. Done it. Everytime, productivity increased! It os only when employees retaliate and government intervention then there is some cost involved to mitigate that. But still productivity is high (as in using the same amount of money to get more widgets and revenue in the same amount of time). You might be young say under 30s. Look back since the Nafta treaty signed in the 90s. There is enough evidence to back me on this productivity/revenue increase for the companies. For American, of course painful layoff.
