With the left's triumphant success of constantly getting more and more of their stuff paid for by other people, they also detach themselves from the real world they would have normally had to have work in. Since there is no consequences to acting like a child your entire life (because the government or rich parents will pay for you to live anyway) more and more leftists are showing signs of simple insanity.
And I'm not joking. This is real insanity. The real world and its harsh punishments should you step too much out of line would keep you operating and sane in the real world. But since punishment (not to mention starvation) has been eliminated in the western world, our people are decaying into the adult children most millennials and leftists are today.
