I'm saying this because lots of people ask "who will buy your products when the people are poor?" to the companies,
but the companies don't actually care whether you buy their products. As long as they have extracted enough out of you that they already own everything, further profits are not a priority.
I'm saying this in the context of people getting poorer and poorer and the current cost-of-living crisis, where companies don't pay a living wage anymore and people ask "who will buy your products when we can't afford to?". It was never about revenue, it was always about ending up owning everything.
Of course they exist, but they're likely not factored in to the cost of the good you're purchasing. The worker isn't going to make any more money if you buy a product. (Unless there's a commission, I suppose)
the cost of the good you are buying is where the workers money comes from
if you (maybe not just you but like 1000s of people) bought something from a corporation, and their profits grow, some of the extra money that the company makes will go to the worker if they unionize for high wages (that the company can now afford to pay) or if the company is forced by the market to pay the workers more so they don't leave the company individualy. And if the company wants to expand they will have to pay more workers to make more products which overall pays them more (but not individually)
there is some trickle-down here and while it is not much its really incorrect to say it doesn't exist
That's fair, but by that accounting it's probably better to say that when you buy something for $10, $1 goes to the worker, $1 goes to the company, and $8 goes to other companies who then pay their workers, etc.
