>>7037669Communism removes the idea of individuality from culture and community in favor of forced conformity for the sake of production. In essence communism teaches you that you're mainly there to produce something and not try to go out your own way.
In National Socialism the idea of free enterprise is still intact. You can still own your own land, own your own possessions and do better for yourself if you work hard to get more.
Communism also calls for class warfare to make one single class but still elevates members of the state above the regular working class. Though their ideology teaches you that everyone is equal in the reality of a communist system some are more equal than others.
The merits to communism is on the small scale distribution of goods to keep the bare essentials. In a small system it makes sense to distribute what you have so that everyone can get their bases covered before delving into extravagance (but communism teaches decadence is bad so don't get more than you need) so everyone for the most part gets to stay alive.
Another merit is how productive a communist state is. Since they've eliminated the idea of anyone being above anyone else say a doctor or astronaut there's no need for the people to waste their time on things like politics or internal occupational power struggles. This makes for a very efficient system that nurtures the natural want of every person to produce SOMETHING.
Downsides you already know starving on the large scale, no individualism, piss poor execution of distribution of resources and basically everything about it going large scale.
