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.

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.

I have long been in favor of a balanced budget restriction at the level of the federal government of the United States. Because the federal government has money-creating powers it can, in fact, be very damaging if it runs a series of budget deficits. With the state government in the United States, they don't have money-creating powers. The automatic discipline imposed by the fact that they are in a common monetary unit and don't have control over the money power means that the balanced budget restriction is less needed.

How would the US be different today if people coming off the boat were greeted with a welfare check instead of a shovel?

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.

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.
