Some countries have had more success than others. It's fairly uneven, and I think it's important to understand that it would depend on the situation. Each person, as I like to say, is a rational economic actor, so they'll look at where they are and ask, is this my best choice?
It might be different if you're in an EU country from what it is in Canada. It really depends on the situation, so I think it's very hard to compare apples to oranges here.
