Corporations are tax efficient, billionaire investors are no different. Eduardo Saverin is a Brazilian, who has settled in Singapore. The only reason he'd retain US citizenship one presumes would be for patriotism or the safety of living in a developed nation. Neither are relevant to Eduardo Saverin.

This piece raises a point raised in Europe a lot regarding tax avoidance (not evasion). Sadly this piece is pathetically vile and borders on xenophobic. It paints the author, zdnet and Dell (the sponsor) in a poor light. It's the sort of comment I'd expect in right-wing reader comments on UK sites like the Telegraph or Mail :-(
