It's literally ragebait to make you post this exact comment without doing any Googling. There are always thousands of "top researchers" leaving America, anyone can cite a civil engineer, nuclear scientist or aviation major and prove you wrong. If your response is "we don't need them anyways" without even identifying a single person in specific, you are (once again) speaking purely from bias. You do not understand the situation and just want to defend pre-established beliefs from popular scrutiny.
