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.

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.

Politicians and bureaucrats are no different from the rest of us. They will maximize their incentives just like everybody else.

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.

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.

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.
