I wouldn't focus too much on the anachronistic technology, that's more to keep with the vibe of the original trilogy.
The farming audits, IMO, are pretty directly an analog to what ICE is doing in the US.
There's definitely some WW2 influence and stylistic choices, if anything that's to keep the execs willing to fund the thing, but later on you'll see some more blatant comparisons to our modern situation.
Something to keep in mind: only 65% of the population voted, meaning only 32% of the population voted for Trump, and he currently only has an approval rating of 40%.
If we compare to Nazi Germany, Hitler had an approval rating of 60 to 70% even towards the end of the war when they were losing.
We're in a much better position to win against them than the Germans ever had against Hitler.
Publicly visible resistance demonstrations like 50501 are going to be more important than ever to help encourage others to also stand up, and show them that there are hundreds of thousands of others who will join them in the fight. A large part of Nazi Germany's success in taking over the country was a lack of massive public demonstrations against the new regime, making people feel helpless and afraid to take a stand..
I know it seems like this just keeps going on, but we have to keep up the fight.
