aeschylus:
"All animals are equal, but some animals are more equal than others." Animal Farm George Orwell
or maybe this one
"We the people of the United States, in order to form a more perfect union . . ." Preamble, Gouverneur Morris
You are nit-picking. There are degrees of equality the same as there are degrees of perfection and I think I will take my stance with those barbarians in determining degrees of either.
Anywho, the scattering of people in India may be closer to the mean than what exists in the US in terms of income and wealth. The US would find a smaller group holding more of the wealth and/or income than the norm as detailed by the Gini ratio. For example with the 2001/2003 tax breaks, 1% of the population received 31% of the tax breaks in those two years. To answer the question of how many people in the US may be classified as poor an/or living in poverty, we can use President Bush's own classification for SCHIP/CHIP or 250% of Poverty. If you look that percentage up in the US Census, I believe you would find an ~120 million people of the population classified as poor and/or living in poverty ubder that scenario.
If we are determined to make a society "more equal" in terms of wealth and/or income; than we are attempting to bring the population closer to the mean. Hence, India may indeed be more equal when it comes to wealth and/or income when compared to the US. Mark's use of "more equal" is proper and acceptable in economical discussions.
As I have pointed out also, the terminology has a historical significance of persective when used to detail degrees or differences.
