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.

Liberals have lost the soul. We haven't recognized the necessity of defending our own system at the level of ideas. We have to get people to treat the idea of a free society as a civic religion or a faith. We need to fight for that faith.

People share a universal behavioural trait: if there are profits to be made, the effort to get that money will attract investment. This is true in the private sector, the market sector, as well as the public sector.

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

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.

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.
