These are complex sets of factors, really. You've heard from several people that it's really hard to pick it apart.
One of the things that I emphasized earlier that's rather interesting is that if you look at the Gini index, the ones that have the lowest Gini index are trying to raise theirs a bit. They need a little bit more incentive for people to try.
I just came back from Denmark. Sweden was number one in the Gini index pool. They had the lowest Gini index. They moved back from that. They had the largest rise in the Gini index so they wanted more inequality to provide incentive.
