Even if you’re were the richest person on earth, nobody wants to live in a polluted city. This is why all of the very rich mainland Chinese love to go to Vancouver; for the fresh air, and nature.
And this is the great tragedy of China; they produce much of their wealth through production, via coal and polluting means. Yet after they establish their riches, they still gotta live somewhere.
The same is happening in Vietnam. The pollution in Hanoi can often be unbearable.
Maybe this is why everyone wants to live in California; even though the emission laws are annoying, it looks like California has been able to curb their pollution.
Also, this is why Tesla and electric cars are such a good future investment; once we could really use solar power, they will lessen the world emissions.
