I suspect that he admires Stalin and Mao because they knew how to deal with dissenters.
Indeed. Bernie honeymooned in the USSR to be close to his hero, Stalin, who was just completing the process of murdering 62,000,000 people. China was in worse shape at the time and so he missed meeting Mao who had murdered 153,000,000 people. But had they met Bernie would have been full of praise for his handling of dissenters.
Gotta wonder how all those yoots are going to like being out of work, in a ‘fully employed economy’ were the minimum wage is north of $20 hr and no one can afford to be in business since the hyper-inflation makes it difficult - especially for pampered snowflakes and metro-sexuals to push those heavy shopping carts filled with trillion dollar bills to the state-owned food store hoping they have enough money to buy a loaf of bread - if there is any left on the shelves.
Go Bernie!

Stalin and Mao’s dissenters didn’t have the ability to shoot back.
