quote - on liberty from John Stuart Mill

  - Action is right if its creates, maintains, or increases happiness; if the happiness of the greatest number of people increases, action should be encouraged; discouraged if action increases happiness for the few at the expense of the many.

     貌似有些道理，但是貌似在中国，小部分人高兴的时候，大部分人也没有不高兴，于是高兴指数还是上升了。等到真的大多数人都不高兴了，这势头就很难扭转了。
