I mean if you're really crazy about money, then sure. But really, contracts within EU pay similar money, and you don't have to become a vampire. The biggest downside is that contracts aren't always extended.

Working with India from the west coast: can we just fucking not? 11.5 or 12.5 hour difference, you're wrecking someone's day every time you have a meeting.

At least on the East coast it's about the same as EE vs West Coast. If you're a night owl on one end or an early bird on the other you can make it work.
