But Falun Gong is 'persecuted'. It is different from other religions. Now, it seems to be an peaceful religion, but Back when it was operating in China, it is not. It seeks political status, motivate its people for illegal activities, and people lost they lives because of it.
I understand you cannot believe me. But ask other Chinese from mainland china, shouldn't be hard to find some if you are in tech industry. (They might refuse to share their opinion because they know the answer might offend you.)
Back to your question, China is not limiting education. But the education is limited by the nature of a lack of resources problem. Lets say we are in a university called US. We have 10 students and 10 Profs in US. Then every student could easily get into the course they want. An entry test might be placed only to make sure the student has knowledge required for this course. But in another university called China, they have 20 students but only 5 Profs. So a entry test is placed on those 20 to select the best 5 students for classes. So these 20 students need to study damn hard for the chance to get into the course they want. For here, prof is a 'limited resource.'
1. Yes - Housing is a problem. I think it is a salary problem. As tech corps in US earns money from the whole world, most Chinese tech corps can only attract Chinese customers. So the value generated from a same piece of code, is better in US. This makes US engineers' salary and status relatively higher in the society than those in China.
2. Yes - people are working 996. But I won't blame the law. I'd blame the culture, or the competitive nature of Chinese tech industry. Union doesn't do anything in China, but labour law does. It is written in favor of workers and executed properly, ask any entrepreneur in China. The problem is, I never seen anyone sued their employer. And there are a damn lot of people that actually working 996 voluntarily without asking by their boss, making the normal ones less competitive if they don't do this.
3. No, I don't agree here. - In tech companies of both countries, I found no difference, relationship does not matter that much even Chinese employees do have a closer personal relationship than US employees. And in other industries like finance, there are no difference either, b/c both countries are 'relation-oriented' in these industries.
4. Yes - I would not say its cruel tho. India, Korea, Singapore are all like this. Its just very competitive due to the limited educational resource and the amount of people who wants to use it. But yea I wouldn't send my child there (If I have one).
5. Pollutions - Sad, Beijing is not a human-habitable place anymore... Shanghai is still okay.
Again, I think the facts you provided are main reasons that stop people going back. Those in the article are slightly wrong(Github, VPN .etc) or not important(foreign business entry barrier) for individuals like me.
