I am intentionally using a somewhat loose term; costs are uses of finite resources. This could be labor, or it could be a physical item, like the iron ore you say I think is retrieved by putting cash in a box. And I’ll pay you the same respect you’ve paid me by asking: do you think workers simply will iron ore into existence? Or make food, independent of the presence of fertile topsoil, water, and sunlight?
Money doesn’t disappear, it goes into someone’s pocket eventually, either through wages or through corporate income.
Yes, and the point is I want more of that money go into workers’ pockets through wages than into owner’s pockets through profits.
If costs are going up it means that someone somewhere is getting richer, meaning he has more money to spend, meaning things get more expensive.
You literally just said that money doesn’t disappear. Someone is getting richer either way. She’ll have more money to spend regardless of if she’s an owner or a worker.
It is true that wage growth does generally cause inflation. That’s one reason you can live in the global south so cheaply. It’s also why workers are so bad off there. Another example is Europe compared to the US: prices are higher in Europe, but workers get paid more and are better off than workers in the US. The whole point is that when workers’ wages go up, they have a bigger portion of the total amount of money, and thus are better off. This inflation fearmongering is all a distraction from that.
