"A survey was conducted in Shanghai where interviewees were asked if they wanted to be a factory worker.One percent of all people interviewed said “YES," Wang Hongjun, a technician, said, raising his voice for dramatic effect."But I can tell you, only a small part of that 1 percent are telling the truth."
I've met colorful people like Wang all over China.They are cynical (玩世不恭的) yet warmhearted, plain spoken but smart.And many of them are confined (局限于) to work in factories.
Wang is a top technician but also represents manual factory workers, who are China's most important natural resource.Their energy is powering China's economic boom, and their muscle is turning the wheel of the world's factory.
But does their unskilled labor give their life meaning? At school, did they tell their friends: "When I grow up I want to work in a factory making socks?" Did you?
Factory work has always been a stepping-stone from farm life to the city and a modern life.It's been happening for centuries, but today, with our space-age technology, it's outdated.Earning 1,200 yuan ($169) per month working in a factory is better than that on a farm, but as Wang points out, it's not a dream career.There should be better ways to earn your rice.
Many modern factories no longer have production line workers.Robots do the assembly (装配).People just do the monitoring.In this age of technology, in which China is now working smarter and not just harder, why are people still standing in production lines?
But life is cheap in China.So why not continue to exploit the low-cost labor situation and keep the economy growing fast, some entrepreneurs may ask.
How many people surveyed really like to be factory workers?
