Why is it easy for landlords to have "stupid sons"?

The so-called "stupid son of the landlord's family" is just an excuse for the poor to comfort themselves. How bad can a child who grew up in a good environment be?

As long as they don't commit crimes, the ordinary intelligence of the landlord's son is the proper winner in life. On the contrary, children from poor families are more likely to become "stupid sons" because of their growing environment and vision.

It's just an example that a pheasant turns into a phoenix. This is a story of successful learning and selling it to you. Don't fantasize about others, look at your savings first.

I always fantasize that the landlord will have a stupid son, and the rich people will not get sick for three generations, so they have to be cured quickly. The seed of money can only be money, not anything else.

In fact, the probability of the foolish son of the landlord's family is almost the same as that of the foolish son of the poor family, but the landlord uses more investment to improve his son's birth defects. Poor families can't change anything by increasing investment, but they can only get rid of the bottom by genetic mutation. This is the origin of the saying that the rich rely on equipment and the poor rely on variation.
