Why should middle-aged and elderly people be cleaning and security guards when sweeping the streets?

From the middle-aged and elderly people themselves, not all of them are doing cleaning and security. A considerable number of middle-aged and elderly people who have jobs are still in their posts, such as teachers, doctors, officials, lawyers and accountants. There are also many middle-aged and elderly people in these industries. Only those middle-aged and elderly people who have no job, specialty and education are engaged in manual labor such as security and cleaning, which is really helpless.

From the age point of view, even young people without education and skills do not need to do security cleaning. Of course, but the security guards made by young people are generally plastic-faced security guards at the door of the sales office, and their salaries are higher than those of older security guards. After all, young people can still eat youth meals and have wider choices, but if they don't have academic qualifications and skills, they don't know how to improve themselves when they are young. When they are old and can't eat their youth meals, they will have a wider choice. Therefore, only by studying hard and improving your gold content can you find a career with higher income, better working environment and more respect.
