What I meant to say, sorry for my poor English, was that there isn't one single reason. Lack of resources is one reason, lack of Guanxi is another, lack of money management skills is another, lack of a mindest to improve oneself is one as well, etc. There are also indirect causes, like not going to the gym, therefore having poorer health, therefore perform worse and spend more money/time on medical treatments. Not having a single dimensional problem means you can't resolve one dimension of the problem and expect the problem to go away. E.g. you give money to a poor guy, he will still be poor 5 years later, you give education to a poor guy, he will still be poor 5 years later (if he even accepts it in the first place). Hard to read was the article because it assumes this multidimensional problem to be one dimensional and then argues that the source is not single-dimension A but single-dimension B. Both is based on an assumption I disagree on, despite all the details possibly being correct.
