>Hiring agreements (collusion) do not involve force or fraud.
Hiring agreements are where an employer uses the power of their position (and those they are colluding with) to control their employees. I would argue this is just another form of 'force'. You don't need to physically harm someone to control them.
A shop that opens across the street from another shop doesn't "force" the other shop to lose money. Your definition of force is contradictory, as it leaves no room for anything that is not pre facto considered force.
