Uh, yes it did. I've been 3 times. In 2002 (first time I went), you were considered wealthy if you're family had a car. 1 car to share!. I just got back again in feburary, and everyone in my fiances parents neighborhood now has a car. In 2002 there might of been 10 cars in the whole neighborhood. There used to be almost no middle class. Now it's exploded, and their middle class is growing like crazy. I can't believe how much it's changed in the past few yrs.
To make matters worse India is almost growing at the same rate.
Here's an article for further proof. Written in Canada in case you think the US government is bull****ing us.
