If you're too weak to crush your enemies you're no different than a judge who let's rapists and murderers walk
It starts with will. Starving them out is the point, do you feed hostile snakes in your house too? Do you know how a siege works? Starve until capitulation
So, your neighbor thinks we should have "public healthcare" meaning putting the State in charge of the health of the people, typically not leading to great results, and a very Marxist proposal. Are you saying your Neighbor now needs debanked, fired from their job, shunned from society, until they and their family starve?
What you seem to forget is that it's Americans we're talking about. And given our school systems still teach Marxism as though it's a good thing, still teach critical theory in it's various forms as though it's real and important, and still fail to teach any useful skills, I'd say targeting the working population is the worst possible thing you can do. That's civil war talk, and not even one that will lead to a positive outcome.
Tear down the completely useless education system, reinitiate Apprenticeship programs, roll back child labor laws so that work ethics can be built PRIOR to high school graduation...
Many things can be done to combat the rising tide of socialist sentiment. Trying to starve your neighbor? Is a socialist solution. Stalin approves.
