Shows how much you know about these kind of topics.

A 7% growth for one country can be bad, while a 2% growth for another country can be good.  It's called potential and China has a lot of that since it's a developing country.
Same reason why a 10% YOY increase of Ouya sales would still be terrible, while a 5% YOY increase for PS4 sales would be quite good.

Comparing China to anything but developing countries in terms of growth rate is illogical.

yeah but guess what its higher growth than most other devoloping countries. Look at india it has 7% growth while china has 6.9% right now, but again China is a lot richer than india now. I never compared it with first world countries but if you do you see that:

germanys and USAs growth is 1.5% now thats a ratio of 4.6x for China having more growth. And GDP per capita in china is 13k $, Germany 40k, USA 55k. Do the math here

Chinas economy is still doing well, you should less listen to US/western propagandas wishfull thinking (yes they want 1 billion people to fail and being poor).

China is gonna provide million of pretty asian girls who when I'm 50+ will be 20 and yet you guys are scared for the world... prioritize people..

This is very much the case with China.

Makes little difference ... 

It's socially fashionable to have one children because of life quality increase ... 

This isn't entirely new. Restrictions on one child policy have been around for years. As China has grown the cultural norm of one child still remains and raising children becomes more expensive.

What you want ideally is slow and steady population increase. China had a population explosion in the 20th century, doubling from 1950 at 600 million to 1.2 billion by 2000. However, in the 21st it looks to level and even decline given current aging demographics and socio-economic factors.
