As a non American can I say, does bernie ever actually propose plans or ideas or does he just go around shitting on bad ones?

Edit: why am I getting downvoted as an outside observer asking a question. It’s concerning that Americans have this NEED to be part of a cult. The right has Trump and many on the left have Bernie. If you dare to question Bernie even a little, or simply ask an unbiased question, and you get piled on.
