I made a reference to both Hitler and Stalin recently in regards to trump being considered "not that bad" by a poster. Bringing up Hitler is not off limits IF there is a strong point being made to compare patterns of history. What I stated was how both Hitler and Stalin did excellent jobs as leaders early in their positions. Both made substantial improvements to their nations because they didn't have to account to something like a Congress. They both identified problems and they made decisions, and those decisions were implemented. The USA system gets stifled because there is debate, and many good, and bad, ideas don't get implemented because there is a compromise.
The USA would be vastly improved if we had a dictator who said there would be strict rules for dealing with the pandemic, for more fair and equal tax rates, higher minimum wage that is increased in different ways and over time, universal healthcare, and so on. We can look at the anti-immigrant polices of the trump administration, and how many of their policies violated domestic and international laws, as an example of extremist views that were to some degree buffered by liberal laws. Who knows what would have happened if trump had no accountability to congress, or no fear of the law and consequences (beyond his indifference to corruption and fraud which he has largely gotten away with thus far).
