One of the pieces of data that turns out to be nearly impossible to find is a direct comparison of the median income by quartile on a PPP basis between countries. In other words, how does the income of, say, the US lower quartile compare to other countries? There are a zillion sites with metrics of income inequality and GINI indexes and such, but to my mind these are meaningless. OK, the poor in the US are much less wealthy than the rich in the US, but how do they compare to the poor of other nations. The few studies I have seen have reluctantly (remember, these are leftish academics) admitted that the US poor do pretty well vs. the poor in other nations. Here is data for US vs. Europe.
I got a lot of grief a few years ago when I said, related to Kwanzaa:
Every African-American should wake up each morning and say "I give
thanks that my ancestors suffered the horrors of the slavery passage,
suffered the indignity and humiliation of slavery, and suffered the
poverty and injustices of the post-war South so that I, today, can be
here, in this country, infinitely more free, healthier, safer and
better off financially than I would have been in Africa."
I wanted to actually make this comparison more real. I used the CIA Factbook to estimate the share of per capita GDP on a PPP basis earned by the top decile, or top 10% wealthiest individuals, in a number of African nations (Example page here for Ethiopia -- calculation would be [25.5%/10%] x $700 per capita).
So here are the results:
- Ethiopia top 10%: $1,785
- Nigeria top 10%: $6,972
- Zimbabwe top 10%: $800
Hopefuly this is enough of a sample to give you an idea of the range. Only South Africa is a real outlier from this range. Now, by the same methodology and source, here is the average share of the per capita GDP for the bottom 10% of earners in the US:
- United States bottom 10%: $9,160
- United States African-American avg (est): $32,060**
Wow! This means that the average person in the bottom 10% in the US, most of whom we classify as below the poverty line, would easily, by multiples and orders of magnitude, be in the top 10% richest people in most African nations. And the surviving decedents of those poor folks who got dragged to the US in slavery would be the Bill Gateses of their mother countries.
The point being, of course, that the size of the pie is typically more important than how you divide it up. And it is nearly an axiom that government efforts to divide the pie more evenly almost always make it smaller.
** estimated based on 2006 median black household wages being about 70% of the US median household wages. Yes, I know, we are wildly mixing apples and oranges here to get African American share of GDP per capita in the US, but its in the ballpark -- certainly close enough to make my basic point. And yes, I know there are flaws in measuring income across countries even on a PPP basis. If anyone knows of how to get this data more directly, please email me.
