There is no such thing as “shipping jobs overseas.” “Jobs” aren’t a thing. You can’t ship them anywhere. You can’t own a “job,” and no one can “steal” a job from you. A “job” just means that someone has decided to trade money for your services. It doesn’t mean they have any obligation to keep doing so.
People who have chosen to trade with you in the past can decide to trade with someone else instead. While this may be inconvenient for you, this is not an act of aggression against you. It doesn’t make you a victim of anything. You have no right to a “job,” any more than the local convenience store has some right to have you buy lunch from them.
Speaking of which, unless you go out of your way to spend more money on inferior products and services, it is hypocritical to whine about anyone else looking for a better deal somewhere else. If someone in Mexico or China can do what you do, at a lower price and/or higher quality, then people should trade with them instead of you. And if you want the force of “government” used to prevent that, for your benefit but to the detriment of everyone else, you’re an immoral twit.
