The solution, of course, is to ban private tutoring. Just like they did here: https://www.sixthtone.com/news/1008838
Plus a ban only extends to within a country so people in other countries will go right ahead with their tuition. Competition is global and such bans, beyond dismantling the tuition "business" and putting up hurdles in front of parent's craze for the rat-race, don't do much. Nobody is talking about the root cause, which is the fear of unemployment due to scarcity of opportunities.
All the while, the very well-off will continue to manage perfectly with plenty of workarounds available to them, as usual. All these bans would do to create another class of have's and have not's.
