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.

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.

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.

America is perhaps excessively mobile in the sense that there is sometimes not enough stability in communities. Dynamism in the economy is not necessarily the "be all and end all".

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

You can get a coalition of senators from particular states in America, for example, who want to construct highways or dams or ports which may well be very inefficient. The taxes would be paid by the people over the whole country, but the benefits would go to the few people in those particular locations. This type of spending is a rather gross waste of resources that worsened over the years as the government has been allowed to do more particularized things.

Imagine that Queen Elizabeth I, in her time, had the opportunity to give out a monopoly for playing cards within the kingdom. She knew she was going to give it to one of her courtiers. These courtiers would then all try to curry her favour. Meanwhile, they would not contribute anything to the product of the kingdom, in fact, they were wasting resources trying to secure a single prize. That, more or less, is rent seeking.
