Does Basic Income + VAT “Solve” Immigration?

One of my favorite liberal policies is the basic income proposal. The idea is that all citizens have a basic guaranteed income, below which no one may fall. As the argument goes, this supplies more flexibility than basic provision of essential services, and renders recipients much more autonomous than they currently are, since the government tends to spend redistributed money on the things it values the most, rather than the things that the poor value the most. There’s also a fairly easy way to run such a program: instead of making the basic income available only to the poor, you can make it a citizenship grant available to everyone who files tax returns, like social security. This radically simplifies the administration and eliminates the wasteful need to inquire into the deservingness of the recipients. If you’re a citizen, you get a check. Alaska has a system like this for all residents.

As I wrote recently, the dark side of the basic income proposal is that it privileges citizens over non-citizens. Perhaps this dark side is mitigated a bit if every nation-state in the world enacts a basic income, but there’d still be horrible inequalities between nations. However, in this post I want to argue that this kind of inequality is better than the status quo: “second-best” ideal theorizing… with a dash of public choice caution for good measure.

How Taxation Effects Income Share (Not Much)

Last week, Greg Mankiw posted this graph without comment:

I thought there was something weird about the graph, and it’s been nagging at me. For one thing, it compares the bottom four quintiles to the top 5 percent of Americans. For another, it ignores non-federal taxation. (State and local taxes are more difficult to calculate, I suppose.) So I dug around and found the data* to produce this graph, which compares the share of income earned pre-tax to the share of income kept post-tax. It still only counts federal taxes, but it seems a more honest graph:

Two things are noticeable right away: the top quintile earns more than half of all income in the United States, and only the top quintile loses ground relative to its pre-tax share because of federal taxation. Many goods consumed by the richest 20% of Americans are signalling goods, and thus only valued comparatively (nicer house, better clothes, fancier car, more exclusive schooling for one’s children, etc.) But of course not everything is pure signalling, so relative inequality may be less important that absolute inequality, just as relative wealth may be less important than absolute wealth. Not everything is about keeping up with the Joneses. So if we can bypass these questions of fairness and move on to the relevant question, which is how large a GDP it is we’re sharing, I think that would be good. Tax policy will certainly have implications for future growth, but let’s not feel too bad for the top quintile.
