There have been any number of MSM stories based on StatsCan's recent release on earnings and income. Median earnings from market income for individuals in 2005 are pretty much the same as they were back in 1980, and market income inequality has - by any measure - increased over the past 25 years.
This isn't really news - at least, not in the sense of 'revealing previously unknown facts'. Here are plots of average and median market income for unattached individuals and for for economic families of two or more people; the data are taken from Statistics Canada's Cansim Tables 202-0202 and 202-0203:
Although median market income in 2005 was the same as it was in 1980, it hasn't remained constant: the recessions of 1983 and especially 1991 reduced real median incomes considerably, and it's taken ten years to recover. And the widening gap between the average and the median indicates increasing inequality during this time; something we knew about already (see this post, and this one, among others).
Inequality in market income doesn't bother me much in itself; what really matters is inequality in income after taxes and transfers. If policy-makers are responding to rising inequality by improving its programs for redistributing income, then the effect on inequality of disposable income will be a wash.
Unfortunately, that's not what has been happening in Canada. Here is how net transfers have changed; the data are taken from Cansim Table 202-0704:
Net transfers to the highest quintile have decreased; income growth has been concentrated at the top end of the income distribution, so their tax payments have grown in proportion. But the main beneficiaries are not those with the lowest incomes; the increase in net transfers has been concentrated on the middle income groups.
Here are how the shares of (gross) government transfers have changed over the past generation:
The share of transfers to the lowest quintile has decreased since 1980, as has - albeit to a lesser extent - that of the second quintile. The winners in this reallocation are the middle and fourth income quintiles.
It's not hard to imagine an explanation for this; the median income group is likely to include the median voter. So every political party will be happy to sacrifice the lowest income group's interests (that group is either taken for granted or written off entirely) in order to gain popularity at the centre.
Reductions in welfare and UI benefits in the 90s reduced distributions to the lowest quintile. I don't recall specific numbers but I know at one point the effective marginal tax rate for workers in the lowest quintile was in the 70-90 percent range. This was due to the loss of welfare and other benefits as they joined the workforce. It should not be surprising that this shows up in the gross transfer numbers.
