VN is developing nation, we don't say we r rich like a "super power" CN, having 600 million Chinese earn less than 140 usd and staving on streets like in N.Korea cos CN banks are bankrupted
Again - those 600 million have a "
DISPOSABLE INCOME" of US$ 140 - it has nothing to do with a direct income. Since many of these countryside and rural town people don't even have regular jobs - but work on their farmland and as such no "registered" income. Also usually a person below the age of 20 and those above 55 do not work but are pensioners or students. Not to mention kid raising mothers with not wanting to take jobs. But they are financially supported by the government, their own relatives and selling e.g. products from their farmland, or taxi service with their scooter, etc. etc. - that is not registered as an income. Many times my family and me travel to farms around Shanghai and buy farmland products (not cheap at all) - no one ever gave me a receipt nor did I ask for one.
So out of your 600 million - around 400 million are not even legible for a job - respectively income.
You want to know about a countries actual wealth go and check the GDP figures and keep in mind that in China this GDP is used in huge sums to support the rising of living standards - similar to Communist Vietnam - and totally different from e.g. Indonesia or Philippines were the government and rich couldn't be bothered about their own poor and additionally lack the GDP to do anything much about it anyway.
One can only compare China overall with e.g. the EU or Europe - look at the size, population and diverse infrastructure - even then China still dwarfs them.
You have a GDP/capita in Germany of US$ 51,000
You have a GDP/capita in Ireland of US$ 103,000
You have a GDP/capita in Romania of US$ 12,000
You have a GDP/capita in Poland of US$ 13,000
You have a GDP/capita in Bulgaria of US$ 8,000
You have a GDP/capita in Serbia of US$ 4,800
And China with 1,4 billion people can show a GDP/capita of US$ 14,000
Meaning e.g. Shanghai is on par with Ireland, the Eastern Sea-bound provinces are equal with Germany, whilst those in e.g. Gansu, Qinghai or parts of Sichuan are on par with Bulgaria and Serbia.
On average GDP/capita China is on par with Poland - and Poland is not regarded to be poor at all in Europe. Even though 17% of Poland's population is below the poverty world line of US$ 1,90 a day. And US$ 1,90 a day in Poland is equivalent to around US$ 8 a day in China - it's called buying power.
As such a "poverty stricken Chinese" can afford to buy 4 times the items a Polish poverty stricken person can afford.
