How did the saying "You can't be rich for three generations" come about? Why was it so difficult for wealth to continue from generation to generation in ancient societies?

The saying that wealth is not passed on through three generations is a very famous comment on wealth inheritance in traditional Chinese culture. So how did the saying "no more than three generations" come about? Why is it so difficult for wealth to continue from generation to generation in ancient societies? There are several reasons.

First: three generations in accordance with the age of a generation of 70 years old, 210 years, just most of the prosperity of the dynasty to the demise of the time, any economy can not cross the times and the wheel of history, the trend, is the biggest reason.

Secondly: there is no wise leadership in the clan, leading the industry to achieve new glory, or there is wise not in power, there is no fair talent selection system. This reason occupies the second main factor.

Third: the ancestral industry can not adapt to social development.

Fourth: the more widely circulated, the second generation of the third generation of rich people do not do their jobs, corrupt the ancestral property. In fact, it occupies a very small part.

Fifth: rich but three generations is a traditional saying, in fact, in giving the world a reason to work hard, admonishing the poor, the bottom of society, you have the opportunity, they rich people sooner or later to become poor, so the poor people choreographing the most is dude. Cover up the human class solidification, cognitive solidification, thinking solidification. So wealth is difficult to continue from generation to generation in ancient societies.

Sixth: dynastic turnover and the laws of the economy, talent selection system is not perfect, family business disease, dude. It is true that all exist, but these are not enough to make the rich (elite) within three generations to the poor (bottom people). This is the fact that perception, then incompetence, perception and exposure to the environment will be passed on. The system in bad, from the environment, the rich are exposed to most of the material are poor people lifelong did not feel. From the cognitive (thinking level) to consider, the rich is from the top to the bottom, these two inheritance, from birth is doomed.

So my conclusion is that most of the rich hang around in the middle and upper echelons of society, they just aren't as prominent as they were at their peak, and very few fall to the bottom. The poor are still mostly hanging around the bottom and middle, with very few reaching the top of society.
