Can you become crazy?

Jean-Jacques Rousseau writes the social contract. This book consist of an equality and rights of persons instituted by the government.
This book(and a lot of films) give me some ideas. The society influences people to make them mad?
I think that: The society can control all about the persons, for example, If you have some friends they can pressuring you for change some ideas.

Here i put some examples.
1) The politicians uses the society for get some political votes. They give a lot of promises but the only do 1 or 2 showing illusions to the people for get the power.

2) The violence in the culture: I can't imagine a world without violence because has been educating me in this way(I receive the information each day (for example) in almost all series appears "the sexual game".This generate a sensation who affects you personality( are transforming you psychologically healthy)

3) This society is already beginning to select the best people, for example, when preparing a select only the best are chosen because it is superior to the others (it looks like natural selection of Darwin). This selects generates psychological distress that can't heal (the inferiority sensation).
In my opinion the society control our lives and We can't do anything for change it. Finally If the society are pressuring you-for become mad-you will be mad.
