How does that work when all of the production happens in other countries now? Is there some scenario where we have a socialist white collar economy? All the rhetoric surrounding Communism fits a blue collar economy where production is still the key driver of the economy. Most “1st world” economies these days are service economies not production economies. Is there some literature on how Communism fits in with a service economy?
You can try WhoBird. It’s open source (available on fDroid) and runs completely locally on the phone. I’ve had decent success with it even in noisy environments.
