The Left neither cares about prosperity nor jobs. It cares about equality
The Left has always been anti-religious, and especially anti-Christian.
An unhappy life is a life not lived.
When Jews left Judaism, they didn't stop being religious. They simply swapped God-based Judaism for godless secular humanism and leftism. For left-wing Jews, Judaism is their ethnicity; leftism is their religion.
Happiness is a moral obligation
For the Left, tolerance does not mean tolerance. It means first, acceptance. And second, celebration. That is totalitarianism: You not only have to live with what you may differ with, dear citizen, you have to celebrate it or pay a steep price.
