The salary gap in Europe is *huge*, at Meta and other big tech you can easily make 3x (after taxes) of what you'd earn in a European company for the very same position, same amount of actually worked hours. It might not be fair or might not be ethical, but in particular if you have dependants, such a gap *does* make a difference.
No reason to be that sarcastic, the job market is not dead (at least not in Europe).
