Eduardo is free to do whatever he likes, but I think it's pretty weak. Way to not give back to the country that helped make his wealth possible.
All the "yeah good for him, fuck america" noise in this thread is pretty gay too, especially if you live here. Hate your politicians, Hate your taxes, but don't hate your own country.
We have a lot of problems, We have a lot of waste, but we have a lot of good things too.
The fact is a lot of great companies come out of this country: Facebook, Twitter, Google, Apple, Microsoft. It's not a coincidence. I want my country to continue this into the future.
Want to renounce your U.S. citizenship and go produce new wealth somewhere else? I'm cool with it, you're a free man. I don't think you should pay taxes on the new wealth you create. But to renounce it to try to shortchange the country that helped you produce your current wealth? That's lame.
As for Facebook IPO'ing, is there money to be made? Fuck yeah. But I think the money is in playing the market, not by purchasing the stock and holding on to it for growth.
