When the purchasing power of currency goes down, the people with the most currency actually lose the most, meaning the rich. In this way, there is a flattening effect. In cases of hyperinflation, having 3 million dollars is scarcely better than having 300, and money is revealed to be the apparition that it actually has been all along. The negative impacts of being unable to purchase basic goods and services also acutely affect the working class, but in a lot of cases that's already true in a "healthy" economy.
This is the reason the bourgeoisie is always pulling their hair out about it. It's also only ever used as a pretense to do austerity and extract even more wealth from the working class while cutting basic services.
Since value comes from labor instead of markets or scarcity, inflation also literally wouldn't effect our standard of living in a meaningful way at all if we set in place robust mutual aid networks and centers and divide the labor in a more just way.
When the narratives of capitalist realism and market necessity start to erode, this is actually a good thing, and this is the case with inflation as long as we are organized and prepared to exist beyond the market.
What about the marginal value of money though? If you need $500 to live and you only have $400 due to inflation, you're much worse off than someone who's seen 5 million become 4 million.
Well, you don't actually need 500 to live. You need 500 to pay people for permission to live, permission you don't actually need if you take what you need without paying or have a mutual aid network in place to have your needs met.
And if we had people with guns expropriating the means to live like that inflation would be a moot question.
Inflation is a means to an end and a propaganda tool. Since it's a liberal justification for austerity, no more and no less, why not turn it on its head? If our cries to stop being murdered for a third vacation home are met with violence, then the flimsy justifications against armed resistance and expropriation lose any semblance of authenticity for all but the most entrenched bootlickers.
This isn't novel either - historically the only time we were very close to a revolution in the US was during the Great Depression, where money couldn't do much for you even when you could get it. That isn't to say that the conditions being awful are a positive thing, but rather that when they are, as they are now, the collective fever dream of the omnipotence and omnipresence of the market begins to dissipate, and many of us won't starve for vampires who could care less if we wheeze to death in a gutter somewhere. The suffering necessarily concurrent with crisis is bad, but we didn't and don't cause that. It is a result of the violent and unjust system that cannot support its own weight. When it topples, we should celebrate and seize the opportunity to move beyond it, rather than justifying the very same logic that's killing thousands of our coworkers every single day right now.
Freeing yourself from the market takes either lots of money, or lots of knowledge, time, and resources. Probably an equivalent of at least $10,000 per person, if you convert all the labor to USD.
