I strongly object to the purchase of the Chicago Stock Exchange by North American Casin Holdings. North American Casin Holdings is a subsidiary of Chongqiing Casin Holdings in China. There is no such thing as a private company in China. All economic activity in China is entirely controlled by the government. China is a command economy masquerading as a market economy. China has nothing but contempt for the United States, our economy, and our culture. Do not give such people a foothold in our economic system: Do not approve this purchase.
