We want to limit the exploitation of the fiscal capacity of the richer regions by keeping down the rate of immigration to a level that would be meaningful and efficient. One way to do that is to have a scheme of equalization which essential bribes people to stay in the poorer regions.

If you create an artificial scarcity through public policy, artificial rent so to speak - setting up a new import quota or giving out a particular office that is very beneficial - people are going to invest money, time and resources in trying to secure that opportunity. If the value is created independently of the search for it, the search for it is wasted.

Politics is a romantic search for the good and the true and the beautiful.

Politically, sometimes you get situations where rent control will go through. It is especially true in an emergency, where there is a sudden, sharp increase in demand for housing or a cut back in supply. People will simply not allow the marketplace to allocate housing resources and so you get pressures for rent control. Once you have it, it is hard to eliminate.

It is much more difficult to get implemented politically what might be desirable economically. Even if you came out with an economic argument in favor of equalization - and I think there are arguments on both sides - I would still come down in favour of some sort of a scheme on strict economic grounds.

If you have an area where high-income receivers concentrate, you have a higher fiscal capacity. That fiscal capacity is a valuable resource and will create rent-seeking. People will trying to get that resource one way or the other, including immigration. It is very much like the medieval peasants putting their sheep on the commons pasture. It is better than the open range, and if you let them have open access they will, in fact, put too many sheep on the pasture and waste the value that the pasture has.

I think the world has changed dramatically since September 11th. It should force us to recognize that we are going to have to defend the free institutions of our society against those who are simply not willing to belong to a civil order.
