Talking about "technical staff and white-collar workers are the main force in purchasing pirated products"

I just read a piece of news in donews ,《 Research: science and technology personnel and white-collar workers are the main force in purchasing pirated products ", The news said:

A survey conducted by the Institute of Publishing science of Nanjing University shows that the education level and income are directly proportional to the proportion of piracy purchases. The group of technicians is actually the main force in purchasing piracy!
......
According to a survey conducted by the South University Institute of Publishing science, the proportion of people who have Master's degree or above who have purchased pirated products is 78.6%; the proportion of undergraduate courses is 65.8%; the proportion of specialists is third, accounting for 52.5%; and the proportion of high school students is 50.0%. Looking at the income situation, if the income of Nanjing people is more than 4000 yuan, the proportion of pirated purchases reaches 75.0%. if the income is between 67.4% and Yuan, the proportion is. If the income is between and Yuan, the ratio is 66.7%. The two data items indicate that the higher the education level and the higher the income, the more enthusiastic the purchase of piracy.

The report does not show how big the sample data is? Which cities are investigating? Is it an ordinary provincial capital or Beijing or Shanghai? How many people have they investigated? Therefore, we will ignore this issue for the moment.

Based only on the results of the survey, it is concluded that scientific and technical personnel and white-collar workers are the main force in purchasing pirated goods. Therefore, it is extremely irresponsible that "high-income people become the main consumers of pirated goods.

ArticleWhen it comes to the question that "high-income people have enough income to buy genuine products", the data source involved in the investigation is Beijing, Shanghai, or other places. The income of each city is significantly different from the actual purchasing power. In Xi'an and Chengdu, the income of 3000 yuan may be able to purchase non-very expensive non-pirated items while in Beijing and Shanghai, I don't know how much balance can be paid in addition to living income? These are unknown to some of our experts who don't know what to do.

Individuals do not intend to promote piracy and do their best not to use piracy. However, individuals are reluctant to see such irresponsible publicity. I think researchers or white-collar workers buy pirated products because they are using these products. For many ordinary people who do not use computers or software, they do not need to buy software or other materials, this is self-evident because of the small denominator ratio. For average people, 100 people only have 50 people to buy software or other things, 49 of them buy pirated software, the proportion is 49%; but for 100 white-collar workers, 90 people are buying software or other materials, among them, 80 people are buying piracy, with a ratio of 80%, which is averageAlgorithm. Is this calculation in this article? We do not know whether to use 49/50 = 98%, 80/90 = 88%.

From a group of data, to conclusions, to moral character and morality, to policies and national policies, is it too rash ?!
