What was Alexis de Tocqueville's biggest criticism?

Tocqueville was one of the first social critics to examine the situation of American women and to identify the concept of Separate Spheres. The section Influence of Democracy on Manners Properly So Called of the second volume is devoted to his observations of women's status in American society. He writes: "In no country has such constant care been taken as in America to trace two clearly distinct lines of action for the two sexes and to make them keep pace one with the other, but in two pathways that are always different."
