The Accidental Kenyan: What Would Happen If the African Nation Copied U.S. Tax Policy?

The accidental Kenyan: What would happen if the African nation copied U.S. tax policy?:
This is absolutely brilliant, but I doubt there are any US politicians who would give a damn. I would love Kenya to adopt this, but only on a "reciprocal" basis. That is, "we're going to tax our citizens abroad the same way that their resident countries tax them".
Actually, some Americans would like that because it means a handful of Kenyans would leave the US, but other Americans might finally wake up and realizing how they're punishing the American diaspora.
