Are you talking about the Peter Theil thing? I think it's fair that people who don't like watching billionaires exploit the rest of us would be equally pissed about Eric Schmidt dodging taxes.
The US had segregation until 1964. It's pretty much done non-stop military adventurism since it's inception. Yes, most countries are unethical and morally repulsive, but the US is at the very top of the heap and it has been for a long time.
1. It's unfair for the US to tax it's "citizens" when they no longer live in the country.
2. Billionaires can only become billionaires through exploitation and now some are using this to further shirk any sort of social responsibility or paying back to the systems that created them.
The real problem is that we've allowed billionaires to exist.
