All monetary transactions involve one party wanting to charge as much as possible and another wanting to pay as little as possible.
But most of them don't involve negotiation.
Instead the just involve the threat that if the offer/price isn't good enough, the applicant/shopper will go elsewhere.
What's backward in the labor market vs the grocery market (etc) is that in most cases the seller sets the price and the buyer takes it or leaves it, while in this case it's the buyer setting the price and the seller can take it and possibly cut costs or accept losses if they do, or else go out of business.
The labor market right now is like a grocery store where every customer walks in, picks what they want to buy, offers some money for it, and just walks out if the store wants more than that, so the stores for the most part just have to take whatever customers will offer for their goods (and if they can't afford to stay in business like that, tough shit for them eh?)
