I hear a lot of libertarian geeks complain about the unfairness of the progressive income tax or the welfare state, but not so many complaining about the unfairness of our immigration policy. Then you must run with a different tribe of libertarian geeks than I do. I'm a libertarian geek. And I complain about the unfairness of our immigration policy constantly. A few of the best hackers I know are from other countries. I completely disagree that I'm "at risk more than I gain" from increased immigration. If they can do as good a job as me for less money, then that's the market, and I'll have to accept that. But really good programmers -- the top 5% that are 5-26 times more productive than the rest -- are always going to be rare, and it's worth a pay cut to be able to work with them. Incidentally, with our current system, tech workers are often given a visa that is only good for the duration of their employment with a single company. That means, if my coworker wants to go to another company, he has to get a whole new visa, which is incredibly non-trivial. As a result, my employer can skimp on his pay, because of the added cost of changing jobs. If they pay immigrants less, then that brings down the whole market, including my salary. If our doors were open, we'd have more immigrants, but they'd be more able to negotiate, and we'd all be on equal footing. More people means higher housing costs, the weight of which tends to spread out the population distribution and make workers more demanding.
