At a 2x difference it's probably not worth it to have to deal the hassles, immigration, labor laws, relocation, time zones, cultural/language differences (yes, even between US and UK there are differences!). But compared to India, with 10x+ the wage difference? Suddenly it's worth it. I don't think 2x is actually that high a differentiator between any two people doing the same job... it's easy to believe that someone can do the work of two other people, or twice as well as another particular person. It's within a believable variance. But 10x, 25x, 100x...? Not so much. And in fact, it probably suggests where US wages SHOULD be -- similar to Western European ones -- if our market was more realistic and not driven by VC money. Well, with some affordances for our different social safety nets and costs of living too.
