But, I agree with you that the American advantage isn't merely financial.
There's also the fact that start-ups there aren't burdened by onerous labor-protection laws that make it impossible to lay off expensive, high-tech workers, if the business doesn't work out. It's ridiculous that someone making six figures should receive the same legal protections as common laborers, as they should be expected to build up their own private savings. But that might soon change.
