Yeah, that's just them repeating capitalist rhetoric they hear in media (of all sorts) all the time.

Anyone who has access to the pricing for raw ingredients knows how that works. I was always told if some is under $50, double the price. If it's like $100-300 1.5x price. If it's more, 1.25x or 1.10x. Or ask the owner usually. (This was some absolutely scammy job years ago and honestly I think the starting markup was 5x but I can't remember now. Been like 20 years)

(Speaking of my old old job as a far off, non-personal to now example): So you can kinda so the math on just sales you do if you know the company paid $10 and you sold 10 of them for $20 in a day. Plus you did labor repairing equipment which had a contract for repairs agreed upon between the companies worth 6 figures. They value that machine being operable for like 5 years enough to pay $200K (like $300K now days). How much does that mean your hours of labor are worth?

Gets kinda nebulous quickly... BUT you can always be absolutely assured you are still earning the owner profit otherwise you won't have a job for much longer. And owners aren't like "nice guys" who will pay you $20 out of $25/hr total value you might create and they pocket $5. Nah, they're probably making another $20/hr off you AT FUCKING LEAST! Again, there is a lot of speculation in this stuff, but also I mean I've seen pricing myself. They try to obfuscate things but there is absolutely, once you know all the numbers like rent for storage, utilities, etc., some amount you cost per month for them to keep hired vs how much value you create and that equation is always unequal towards the owner and it will be a significant amount to justify the hire originally.
