On a personal level: prepare a bug-out bag and practice migration; hoard enough food to last triple your household a couple weeks; get used to poverty; vote for the leftmost viable candidate in every election and primary;

learn useful skills for a disrupted society such as first aid, de-escalation, crisis counseling, safely preparing nearly bad food, physical endurance and practical strength, mending, DIY, public speaking, herding large groups of people, recognizing "authorities" and other groups' hostile intentions, violence, transformative justice, etc. ;

organize with local anarchists/leftists and wean yourself off the capitalist economy; learn to take care of your own emotional state and how to cope in a healthy way with huge amounts of stress; learn languages that will prove useful in mass migration; etc.

We are human. For millions of years our ancestors have lived through cycles of plenty and famine, surviving plagues and crop failures and massive droughts. We have evolved to handle crises such as this.

You need to look for hope outside of the physical material realm.

For example, people can care more, write more beautiful books and plays, invent a super cool new game that's better than chess, come up with all kinds of wonderful creative stuff...there is no limit to human empathy, meaning, quality of experience etc.

Like, right now in the united states around 60% of the population is semi illiterate and most people are uneducated. There is an absolute ton of progress that can be made on the human development side. There is almost an endless number of things that need someone to care about them.

A lot of our "stuff" doesn't make us happy, it's just dopamine.

Things could be so much better if we could slow down.
