It takes about two days to explore Beijing's new Golden Resources Shopping Mall - the world's largest. Minnesota's "Mall of America" is 4 million square feet. Golden Resources, built in an impressive 20 months and opened Oct. 24, is 6 million square feet. With 230 escalators, more than 1,000 shops, restaurant space the size of two football fields, and a skating rink - the Art Deco mall is a testament in glass and steel to the communist party's desire to create a stable, happy, middle-income consumer class. The cost is between $24 and $36 billion.In developing China, that list includes airports, suburban townhouses, skyscrapers, golf courses, hotels, subways - all of which at one point were deemed a craze by officialdom. Beijing now has, for example, 24 golf courses - despite chronic public-water shortages.While Golden officials first estimated 50,000 people a day.
