Perhaps you are being sarcastic in the parent comment, but United States "screwing" its successful people and forcing them out means that these successful people will no longer contribute to United States, but to their new home country instead.

Without their contributions the Unites States will be less successful, thereby "screwing" everybody in it.

This trend within United States is especially ironic and alarming considering that United States gained its success specifically by giving home to persecuted people from other countries with capacity for success. Conversely, other countries, some obvious examples being Nazi Germany and USSR, were not successful specifically because they forced out their successful people.
