Yes indeed, if one thing US is best at it would be marketing, but what I have explained is only true for the past decade (2000 upwards). Upto the 90s and before the tech boom, it was very difficult to make a good living in India where the only stable choice then was to take up a government job.

The generation before (those born till 70s in India) had to struggle a lot under newly independent India and its socialistic ideals. That generation also created the craze about going away from India to build their careers. Couple this with the civic issues of India (which are still prevalent) and you end up in the popular view about India in the west.

USA's main export these days is culture, so yeah, I'd say marketing is top-notch.
