It is an amazing video explaining graphically the global development of 200 countries, in last 200 years. And the ending of course, all the countries moving sharply to the ‘rich and healthy’ countries. The graph looks more accurate when they divide it between the region of the countries. For example China, the differences between the city and the rural areas is really high, in fact all the countries are just like that.
Of course it is impossible to describe the world in 4 minutes cover up to 200 years. In the graph, they did not divide between the peoples conditions. For example, in the city of China, a lot of peoples lives in cages, literally, and the younger generations live in small compact and uncomfortable rooms, share with tens other peoples.
Theres an article in Yahoo Finance talking about, what is the meaning of ‘rich’ nowadays. Even in 10 years, the definition of ‘thousand dollar’ can change. People nowadays didn’t impress with the millionaire anymore, unless you achieve it in the young age.
