Right and some people weigh 3-4 times as much as others and yet they pay the same price for a plane or a bus ticket. Not to mention that they only get to vote once.
This is not a good argument. I don't assume that the author would propose that China had 4 times more votes than we do. Remeber, only 5 nations are part of the Security Council and each of them can veto anthing she wants.
This will change as the War on Fat progresses. A 300 pound person costs as much to carry in fuel as two 150 pound people, but they pay twice the fare. This is analogous to the cigarette taxes justified by public health care costs.
Not to mention that they only get to vote once.
That's a different issue. I believe the franchise should be granted only to taxpayers and prorated based upon the amount of tax paid (ie. a taxpayer paying $100,000 gets more votes than a taxpayer paying $10,000).
From the article: Tuvalu (10,836). This is the same Tuvalu that is attempting to sue the western world over global warming.
