Ayuh, the systems that are will collapse. For the survivors, they might find they'll have to live a bit more like the Amish. More land, maybe barter instead of monetary economy. Relearning how to do stuff like grow crops, can, sew, cook your own damn food. No more productive individuals financing lazy parasites. One will have to become more self-sufficient.

No more factory farming, disgusting over-processed food, and noxious chemical fertilisers. Not gonna find 70% of the population in hollow point barrier mode, either. (Is that more politically correct than land whale? I'm a bit plump myself, though not in the Krispy Kreme model category. Gotta work on that.)

Probably be able to keep your doors unlocked again. Hopefully the survivors will also realise we're all the same species and not judge people by their genetic heritage. Hey! I'm the only honky-gringo-cracker (Technically 'honky-gringa-cracker'. All noses are chicks in the Spanish language, plumbing be damned.) where I work, and it's not a problem.

I'm too old for this world change, but when I was younger and still the macho bastard I was; I woulda gotten a kick out of it. I'd say it's all good. Being a slave to yourself beats being a slave to our stupid, stultifying gubment and other bottom feeders.
