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.

Via Tyler Cowen:

The Asian
Development Bank presented official survey results indicating China's
economy is smaller and poorer than established estimates say. The
announcement cited the first authoritative measure of China's size
using purchasing power parity methods. The results tell us that when
the World Bank announces its expected PPP data revisions later this
year, China's economy will turn out to be 40 per cent smaller than
previously stated......The number of people in China living below the
World Bank's dollar-a-day poverty line is 300m - three times larger
than currently estimated.

Well, this is a bit sad, as I would hope everyone likes seeing people emerge from poverty**.  But it is really not surprising.  Strongly state-run economies are notoriously hard to measure from the outside, and westerners systematically overestimated the size of the economy of the old Soviet Union.

**  I make this statement because I am an optimistic guy full of confidence in the generally good intentions of mankind.  Because if I were not such a person, and actually judged people by their actions, I would come to the conclusion that a lot of people DO NOT want people in countries like China to emerge form poverty.  Trade protectionism, apologias for looting dictators like Castro or Chavez, anti-globalization riots, anti-growth initiatives, and calls for rollbacks in fossil fuel consumption all share in common a shocking disregard for people trying to emerge from poverty -- often from folks on the left who purport to be the great defenders of the poor.  I tried to explain the phenomenon before, at least among self-styled "progressives':

Progressives do not like American factories appearing in third world
countries, paying locals wages progressives feel are too low, and
disrupting agrarian economies with which progressives were more
comfortable.  But these changes are all the sum of actions by
individuals, so it is illustrative to think about what is going on in
these countries at the individual level. 

One morning, a rice farmer in southeast Asia might faces a choice.
He can continue a life of brutal, back-breaking labor from dawn to dusk
for what is essentially subsistence earnings.  He can continue to see a
large number of his children die young from malnutrition and disease.
He can continue a lifestyle so static, so devoid of opportunity for
advancement, that it is nearly identical to the life led by his
ancestors in the same spot a thousand years ago.

Or, he can go to the local Nike factory, work long hours (but
certainly no longer than he worked in the field) for low pay (but
certainly more than he was making subsistence farming) and take a shot
at changing his life.  And you know what, many men (and women) in his
position choose the Nike factory.  And progressives hate this.  They
distrust this choice.  They distrust the change.  And, at its heart,
that is what the opposition to globalization is all about - a deep
seated conservatism that distrusts the decision-making of individuals
and fears change, change that ironically might finally pull people out
of untold generations of utter poverty.
