There are many EU countries that have some type of golden visa, but for a citizenship Cyprus is the fastest one - AFAIK you can get it in 6 months if you invest $2m. The other countries require years of stay for citizenship. I doubt this has much to do with tax, or that he is about to renounce his US citizenship. It just makes it easier to stay and live in the EU (with family) for extended periods of time, nice extra passport to have if money is no object. I think Cyprus has come under fire for this so unsure how long it will last.
