Tocqueville explicitly cites inequality as being incentive for the poor to become rich and notes that it is not often that two generations within a family maintain success and that it is inheritance laws that split and eventually break apart someone's estate that cause a constant cycle of churn between the poor and the rich, thereby over generations making the poor rich and the rich poor. He cites protective laws in France at the time that protected an estate from being split apart among heirs, thereby preserving wealth and preventing a churn of wealth such as was perceived by him in 1835 within the United States.
