I can see that US is mass-controlling their Citizen as well as China. How many arguments you want? NSA has spied anyone in the earth; Facebook, Google, Microsoft, Twitter, Apple and all the tech companies in US share the information to their government anytime. How many proof you want?
If you apply for an ESTA visa they ask your social media accounts (as optional - like they don't know how to search you)
It's obvious to understand that 1.5 billion people can't be fit in 5 cities. Or you want me to draw it down?
The fact is that in this article, there is no news. We all should take it as example to build multiple cities and not concentrate all the services, industries, workers in one or two cities.
US and Europe suffer this issue and it's quite obvious. San Francisco, New York, London, Paris, are examples of places where the cost of living is so high that even people who have a proper job can't afford to live. Yet, we still put all the companies and the services in the top cities and we create a new class or poor workers that couldn't even pay a rent to live decently.
We like to talk smart, but we act like idiots. I can only see that, at least, in China the trend is different.
If you use a bit of your brain you'll understand.
The top tier Chinese cities are completely packed my people and is not easy to live in, yet, anything is much more expensive and the infrastructure are not suitable enough for future expansion.
China still have hundred millions people who will move from the farms to the cities in the following years. Those people can't move all in the top tier cities building a nation with 5/6 megacities with 50+ million people.
They're trying to make the second tier and third tier cities (10+ million - 5+ million) the place where these people will move and the only way is to block the expansion of the top tier cities
Japan did the same after the WW2 and we're not here to say that Japanese technology sucks.
Just watch your phone, it's probably made in China dude.
