Rent control is one policy that economists universally would oppose. It is a grossly inefficient way of allocating housing space and, of course, it inhibits construction and creates the very thing it is supposed to alleviate. It is one of those things where people simply don't understand simple economics and, therefore, put in for political reasons what will damage the very people that it is designed to help. Minimum wage levels are another classic example.

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.

Once you have an equalization instrument in place, as you have in Canada, there arise tremendous bureaucratic values - bureaucratic rent so to speak - in maintaining the system that you have. To shift to a system that paid the transfers directly to individuals, by having differential rates of federal income tax levied to adjust to provincial fiscal capacities, which would be my preference, you would have huge bureaucratic opposition. People would try to protect the rents they have in the current system of institutions.

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.

The assumption that we can keep societies open and free to everybody is going to have to stop. We are going to have to recognize that some people simply are not qualified and do not want to belong a civil order. Until we begin to make discrimination along those lines, then I think we are going to be extremely vulnerable.

You have to have a government to provide you with legal order, with stability, enforcement of property rights, enforcement of contracts, definition of rules and regulations - the rules of the game, so to speak - and to provide certain shared goods and services, public services. Several people have tried to estimate this and they come out with figures like government spending at 15% of GDP. In the modern world it has gone to 40% or above. So we are way beyond the optimal, and that is easier to say than what the optimum is.

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.
