> Seller's market is a funny way of saying they're not being held hostage for their lives.

Sorry, are you saying that expecting people to work to meet their own needs is them being "held hostage for their lives"?

People being forced to sell their only product (labour) at any price to the first bidder or have that product vanish (hours go by) and starve in a situation with massive information asymmetry where the bidders are using collective bargaining and control the means of survival is not a market interaction.

Pretending like it is is completely insane.

When they are denied the opportunity to easily obtain better positions through structural roadblocks, I would to an extent say this. At a minimum I would say that they are being exploited.
