So naturally this should be regulated like a public service.
That said, just as regular public service jobs pay shit it's not surprising that there are regular conflicts due to disagreements about compensation.
If the ILWU goes on a slowdown strike, the port authority cannot simply fire them all and hire replacements. Firstly, that is outright illegal in America and secondly, there is no competition anyway. The ILWU has a monopoly on the supply of longshoremen. If all the grocers were entered into a cartel agreement to not sell milk below a certain price, then you'd have a point. There's no evidence that this is the case.
But all longshoremen are entered into an agreement not to sell labor below a given price. This agreement is their union membership with the ILWU.
Worked on a project a while back for pricing different qualities of milk and the amount of federal programs, guidelines, and laws regulating dairy markets is extremely substantial.
