There's a good argument to say that sufficiently aggregated marketplaces can launder price collusion, and if we were in such an aggregated marketplace then you could make that argument. But we're not in that situation right now.
The 'Edit:' is even more confusing. If I talk to someone in a profession and I wouldn't take twice the pay they receive to do half the work they do then they deserve higher wages? But that list is huge. Congressmen, Senators, many CEOs, Wagner-group mercenaries, ICE officers, drone pilots. In fact, almost every profession has this 4x effective slippage you're talking about.
