Can we blame them? may be not!

This culture you've been talking about isn't native to the Americans as well. It's something that has grown gradually. As humans we all long for the comfort. The present western culture is all about comfort. Not just the clothes but the technologies too. Imagine how hard it is to wash clothes in Nepal(except a few elite households). All you have to do is dump your clothes and press some buttons here. Who wouldn't opt for the easier way?

The love for fashion isn't new to anybody. Whoever it be, it is very important to fit in their peer group esp. when your going thru puberty. Earlier, our parents and grandparents probably wanted new sarees and daura suruwal/ shirt pant for dashain. Or whenever possible. As time changed, so did our taste. The technology did the same.

Instead of blaming it on the Americans, why don't we learn some stuffs from them? Not everything, may be some incentives....why should i waste my energy blaming others for my poverty? i'd rather concentrate my energy on how to get rid of this poverty?

Yes, the Global corporate culture doesn't care. Need to change is definite----the instinct for survival.
