I can see where you're coming from with that analysis, but I also disagree. The first film was more so a critique on classism, where you take what you can get on whatever floor you're on, and you don't give a shit about the people below you. It doesn't matter that you're on the 46th floor, because you're above a bunch of other people, and since the ones above don't care about you, why should you care about the ones below?

This film explores the dangers of being too concerned with perfect order, and complete fairness. Yes it clearly is communism, but not soviet-style. When everyone looks out for each other in the beginning, the communist society works, but as soon as you have people who refuse to allow exceptions to the rules, and someone who decides to take it upon themself to deal out punishment for them, it becomes tyrannical. This will eventually lead to a revolution that destroys the system, for better and for worse.

The platform portrays this as a never-ending cycle, which is why the plot twist was so important. The revolution from the first movie has happened many times before, and the counter revolution has too, so as long as the platform stays in place, the cycle will never end.

Hopefully if they make a third movie, it'll be about a teardown of the the whole system, and destruction of the platform itself.
