Like many newspapers the author is trying to blur the line between legal and illegal immigrant. The reason we are talking about border controls is because yes most come from Mexico. The typical person who is here illegally is Mexican, over 60% are from Mexico. http://en.wikipedia.org/wiki/Illegal_immigration_to_the_Unit... Add in central America and around 75% of people coming illegally are from southern border. I can understand their motivation. What I can't stand is trying to present BS.
When they author is trying to obscure facts one must wonder what other stats he is omitting or only half presenting.
As for taxes. Yes taxes suck. They also fund a ton of things that make American #1 in many areas. Should Americans abroad pay as much as American at home, of course not. But they clearly should still pay. You have a great passport and can come back to a country that has a wealth of opportunities that are not available in most other places and in some cases no where else. Why should you get to pay nothing while the rest of Americans maintain the great country for you to come back when you please? Maybe we should make it cheaper for people to renounce their citizenship, they are not needed.
Note: I should have made two post splitting comment on the immigration stats and taxes in to two posts to see the up/down vote difference based on the issues.
