(FORTUNE Magazine) – They're crazy about capitalism in China. If you ever had any doubts, consider: To buy stock in the West, you pick up the phone. To buy stock in China, you must first secure a permit to enter Shenzen, the special economic zone near Hong Kong. You then bring 100 yuan, or half a month's wages, and wait in line for three days and nights. Then you get mad. Chinese police used batons and tear gas to contain parts of a fractious crowd of a million people attempting to buy application forms to purchase shares in the exchange's new listings. China's ''savings overhang,'' all that money stuffed in mattresses or tied up in savings accounts earning 2% a year, is estimated at one trillion yuan, or $185 billion. The old stock market was shut down more than 40 years ago, and there are simply too few shares available on the new markets to meet demand. Protesters accused government officials of hoarding the application forms. The violence may give hard-liners an opportunity to slow down the pace of reforms.
