If we must say what a profiteering industry is, I personally think that besides Yueming glasses, there are also real estate, education and automobiles. The high profit of the glasses industry has actually become an open secret. The original glasses lenses are glass products, and it takes time to polish them. Nowadays, glasses lenses are often made of resin, so the manufacturing process is relatively simple. And it's normal for the frame to cost three or four hundred yuan at a time. Therefore, the glasses industry is often a profiteering industry. This is not uncommon.

First of all, talk about real estate. The average salary in Zhengzhou where I live is about 5000 yuan, and the average house price is 12000 square meters. In other words, after working hard for one year without eating or drinking, you can only buy a house with a salary of about 5 square meters. And from the actual situation, the real estate industry occupies the first place in the list of profiteering industries almost every year. Its high profits are staggering. And not only in China, but also abroad, real estate is one of the profiteering industries. Many famous rich and wealthy businessmen started from real estate.

Of course, the education industry is also one of the profiteering industries. Of course, the windfall here does not refer to public schools. Because public schools are controlled by the state, everything depends on the state finance, but most people can afford it. The windfall here refers to some private schools and some counseling institutions. Especially in adult counseling institutions, I once participated in pre-job computer training in a counseling institution. The tuition fee for half a year reaches 20 thousand yuan. And it doesn't include room and board. Actually, let's calculate an account. The tuition fee for a student is 20 thousand yuan. There are nearly 30 students in a class. So the total tuition income is 600 thousand. Two teachers, each with a monthly salary of 5000 yuan, only 6000 yuan including performance. Therefore, excluding the teacher's salary of 72,000, plus the cost of water and electricity in the daily classroom. Generally speaking, it is calculated according to 8000 yuan. Then the profit of this class can reach about 500 thousand yuan, or even more.

Moreover, it is more expensive than some private schools. As far as I know, the cost of private schools is about 10, and the annual tuition for each student is 6000 yuan. At that time, there were 10 classes in the school, with nearly 70 students in each class. So you can calculate the overall profit yourself.

The last thing to say is the automobile industry, of course, not the people who sell cars. Although 4s stores also make a lot of money, they also spend a lot of money, which can't be said to be profiteering. The real profiteering industry is distributed in modification and maintenance. Brother Liu Liu once said that there are two kinds of refitting, one is to get parts from acquaintances and then install them yourself. This kind is not very expensive. The other is to throw money in, so the labor cost of the modification industry can be seen. So in general, vehicle modification is also one of the profiteering industries, mainly focusing on labor costs and imported accessories.
