I think in that circumstance we see a need for lower personal tax rates in total. That doesn't have to be done immediately. One of the effects of signalling, by pointing to a target in the future.... People make decisions based on expectation of future state, not current condition, especially something like moving, changing jurisdictions. So in that circumstance, while we believe the target rate should be lower, we don't believe there is a need to act immediately. In fact, simply articulating that target is a strong indication that will have a positive impact.
