I wonder how much communism Americans take before the SHTF?

Gnarls.

Lots and lots out there that WANT communism. Those are the clueless lazy people. See how they feel when they're working 12 hours a day every day for the privelege to have a roll of toilet paper for five people for the month. Allotted twenty cubic feet of natural gas and twenty kilowatt hours of electricity for the month. Fifty gallons of water per person, a head of cabbage, pound of rice, pound of beans, pound of neck bones, and an ounce of salt for the month.

Probably have to put up with population control, you will be certificated to breed and your mate will be chosen for you. The reintroduction of eugenics should be next with infanticide being widespread to ensure a healthy livestock. Age cap on lifespan, once you are no longer productive you will be eliminated, will include people maimed and disabled on and off the job.

At least the undocked immigration will stop. Then the issue will be illegal emmigration.
