Here is a chart of Federal revenue as a share of GDP in Canada, posted by Livio De Matteo, one of the newer bloggers at Worthwhile Canadian Initiative:
Many a contemporary American libertarian dreams of the day when US Federal spending is confined to ~15% of GDP. However, in the real world this happens in a country that has a fairly robust single-payer basic health care system*, early-childhood-on education initiatives (a previous Conservative government even passed a fairly robust school choice plan that was subsequently killed by a Liberal government after 2 years), and a generally higher level of simple transfers. Some transfers don’t make a whole lot of sense, and kind of get caught in backflips, but nevertheless, there it is. Canada seems to take in ~15% of GDP in taxes, although there is a fit about the budget deficit, which is measured in the happy-go-lucky millions.
I think this lends some credence to the notion that I know Matt Yglesias and Kevin Drum are partial to. That is, ‘largely release people from sources of grave uncertainty (like spells of unemployment, extreme health care and education bills, etc., which can be done at a relatively cheap cost), and sensible market reforms become much more popular’. I can see Canada leading the way in replacing their income tax with a revenue-neutral carbon tax.
But there is a chicken-and-egg story here, as noted by Joseph Heath**:
…it is important to observe that this lack of a correlation [between redistribution and long-term growth of GDP per-capita per Peter Linder's work] does not show that economic theory is false, that incentives don’t matter, and that government cna do whatever it wants. The lesson to be learned is exactly the opposite. One of the major reasons that big-spending governments tend not to be penalized by the market is that, due to their very bigness, they need to operate more efficiently, and they need to work harder to get incentives right.
The US government, by contrast, has a tax code that is seemingly designed, from the ground up, to keep tax accountants and attorneys employed. Our institutional structure is to blame for most of this, but our relatively low individual tax rates (compared to other rich democracies) enable it.
This is an important story since we’re wading into a battle between spending cuts and raising revenue. As I think about the issue more, I notice that few of my complains come from the entitlement state at all, and the ones that do are about the structure of programs, not the programs themselves. In contrast, I have major complaints about the revenue side of government, and still more major complains about the regulatory side of government (at the local, state, and Federal levels). I think a lot of self-styled libertarians or people who lean that way feel the same way. I don’t think that utilitarian redistribution is a bad trade for some of my other goals (which would likely uncomfortably expose certain segments of the population to the cold whims of the marketplace). How about you?
Note: Provincial spending in Canada pushes government/gdp up to ~32% vs ~28% in the US.
