I learned this in my History of Technology course a few years back... Ever since I've been very amused by the outrage over China's disrespect for "intellectual property" on sites like Slashdot.
really? They had forced abortions and internal passports that dictated where in the country you could live? And the US government ran tanks over people who protested?
These things _did_ occur, but they are not the cause of the demise of the Native American.
The mere _arrival_ of Europeans, who carried diseases to which Native Americans were not immune, doomed them. These diseases were rapidly spread to any who traded with Europeans and thence to the innermost regions of North (and South) America. Most Native Americans died of transmitted European diseases long before they had any any opportunity to glimpse a "white man".
The Native Americans were so decimated by the time of the massacres and reservations that entire tribes had to migrate and merge, losing their unique identities, in order to merely survive.
That entry is under "Government Type", not under "Economy". The relevant passage from the Economy section is "China's economy during the last quarter century has changed from a centrally planned system that was largely closed to international trade to a more market-oriented economy that has a rapidly growing private sector and is a major player in the global economy."
This may be confusing, because communism is both a political and an economic system. China could best be described as a one-party communist state with a free-market capitalist economy. However, the article is the economy, not the government. These complaints wouldn't be an issue if China was really Communist - the recent uproar has been about a lack of government regulation in product manufacturer, while a truly communist government would manufacturer all the goods itself.
