Your small local company does not own your workers. If the multinational values your workers more than you do, then it is good for everyone except you that they work for the multinational.

But, conversely, the multinational values your workers because it knows how to use them for business opportunities elsewhere to make money. But you're in a position to find many of those same opportunities. Which now means that your local economy is not just getting the profit of having the workers do so well, but of the fact that you're keeping the profit margin that otherwise would have gone to the multi-national!

Free trade on average makes everyone richer. (Observation originally due to Ricardo.) That means that it brings both opportunities and risks. And the opportunities usually exceed the risks.
