2. Income problem. I don't know which large legal enterprise you are interested in and what the treatment is. However, in China, if it is an influential school in law, the basic salary should be around 10W after the associate professor is awarded. In addition, law is an experienced industry. When you have been in the industry for a long time, various lectures, part-time lawyers, projects, independent directors, consultants and so on. It's all money, not to mention other investments made because of sufficient disposable time. At least as far as I know, it is common for college teachers in my old school to earn 200,000 to 300,000 yuan a year, and it is not uncommon for those who are willing to be a little tired. I don't know much about legal affairs, but I don't think many people can do it.
3. Hidden welfare. Universities are one of the few units that are allowed to raise funds to build houses, which undoubtedly saves a lot of pressure on the cost of living (although it seems that it still needs to be shaken). Many universities also set up kindergartens, primary schools and middle schools. Basically, the problem of children's education and study is solved by a train. There are many other hidden benefits. Different schools may have different policies.
