What is white collar, blue collar, working class?

Ma Qiufeng: The concept of blue-collar has not been carefully examined, but we have read some books, this concept was put forward in the United States in the fifties, when the United States entered the information technology. The social ruling class of the United States of America on the blue-collar refers to those engaged in manual labor, such as production workers, engaged in blue-collar workers for the first time lower than white-collar. So blue collar according to the sociological concept of understanding is engaged in physical work, this time I listened to Mr. Duan, times are changing, I think the concept is also changing. Today, we have a different understanding of the blue collar, blue, blue, blue, blue, blue, blue, blue, blue, blue, blue, blue, blue, blue, blue, blue, blue, blue, blue, blue, blue, blue, blue, blue, blue, blue, blue, blue, blue, blue, blue, blue, blue, blue, blue, blue, blue, blue, blue, blue, blue, blue, blue, blue, blue, blue, blue, blue, blue, blue, blue, blue, blue, blue. Deep blue means people with certain skills.

I don't think blue collar should include engineers or senior professionals. It still refers to a larger segment of society that is more engaged in the front line of production. If you look at the discipline, blue collar includes the working class, but they still have some technical expertise. Sharp blue should be between white collar and blue collar. In terms of income, blue-collar workers are not necessarily lower than white-collar workers, as reflected by many surveys in the United States. Sharp blues actually earn more than the average white-collar worker. White-collar is the average office member, so-called white-collar, most of them work in the office, and there are classes of white-collar in office work.

There is also the gold collar:

The gold collar class is a highly concentrated class of social elites, aged between 25 and 45 years old, well-educated, with a certain amount of work experience, business planning ability, professional skills and certain social relationship resources, earning an annual salary of between 150,000 and 400,000 dollars. This class does not necessarily own the ownership of the means of production, but owns the most important technology and management rights of a company.

The gold-collar class is usually the senior management of three-funded enterprises, the Chinese representatives of foreign organizations in China, the managers of larger private companies, senior leaders of state-owned enterprises.
