99% of cases, we started out without regulation, but then something bad happens what made us create the regulation.
In china everybody might be able to cut hair, but also anybody is able to drill water wells, and cause massive sinkholes and subsidence all across china. In china you can pollute all you want, and the citizens just have to deal with warnings about toxic air outside on the weather forecast.
Also I'm sure that if you were to ask an actual barber about that licensing they would be able to tell you plenty of good reasons for why that exists. It's not entirely impossible for a barber to screw up somebody's scalp when bleaching their hair for example.
Ah okay, so you ask them why, and if they don't give an answer you agree with, you conclude that you're right anyway and they secretly have an ulterior motive? What kind of answer would be able to change your mind?
So really, if you're just anybody and start polluting, you'll quickly be stopped. Meanwhile the state-owned steel mill next door has been blasting out unfiltered coal exhaust for decades.
I don't mean offence, but how would the average person (me) in the West know if what you wrote above is true or not?
> The standards detailed in the action plan focus on several harmful substances, including particulate matter (PM2.5 and PM10), sulfur dioxide (SO2), nitrogen oxides (NOx), and volatile organic compounds (VOCs). Each of these pollutants has defined permissible levels, which are critical in guiding both regulatory authorities and industries in their compliance efforts. Over the years, the Chinese government has intensified its efforts to monitor real-time air quality and ensure adherence to these standards
Now try to reconcile this with the actual air quality [1] [2]. Note that September is far from the peak, when it gets cold and dark the air quality in many megacities becomes off-the-charts toxic.
This leaves two possibilities: either the state is too weak or too corrupt to enforce these laws. Since the PRC is far from weak and its organs are very powerful, this only leaves one possibility.
