Bush was never known for his intelligence and accuracy, so this would hardly be the first time someone has suggested that.
Regardless, I don’t really see how he was mislead. As I already pointed out, the term “middle class” is highly subjective with varying definitions (which is why I specifically avoided using the term…you’re the one who dragged it into this discussion). If you set the standards low enough, then the figure he gave for the “middle class” is valid. But, again, that’s not what we were discussing. We’re talking about people with enough disposable income to be a major market for American and European companies, and I stand by my original estimate.
I’m also suggesting that you would be utterly delusional if you actually thought there were anything near 300 million people in India with incomes comparable to that of the American middle class.
