That's the beauty of capitalism. You can just let it run its course and not worry about it. If something is less efficient, it will not be able to compete in the market for very long.
Having said that, there is nothing wrong with employing more people, as long as they are creating marginal economic value. Hiring 10 people to make $10M is better than 5 people to make $9M for a company.
