If I, as a property holder, personally decide to use some mechanism to assist me in reaching a price for my product, that is fine -- even if you don't like it.
If I, as a property holder, meet with all of my fellow property owners and collude to set a market price (eliminating competition), that is not fine -- that is collusion.
Are you claiming that all property holders are literally colluding to establish a price that eliminates a market price? That there are literally no people who decide to set other prices for equivalent products in that market? If everyone in a market decides (with the help of a program, or because they can do basic mathematics) to set a higher price, and some people, like, just read the "for rent" adds and set similar prices -- that they are, literally colluding to set prices?
Because that sounds crazy. What this actually seems to be is the market establishing a price based on common knowledge.
If crazy banksters and treasury-looting politicians decide to cause massive inflation, crash the house building industry, and higher rent prices are one (obvious) result, I think we should perhaps look to the root cause -- not accuse some poor slobs reading data from a spreadsheet and setting a rent price that recovers the true rental value of their property, of collusion.
If that mechanism is a non-competitive price fixing algorithm with access to non-public information then no, it is not fine.
Real Page also created work groups to facilitate collusion between apartment managers.
"access to non-public information"? What, like the market price of your own personal property, and that the algorithm proposes that you should rent it for a price that yields at least the payment of a mortgage on the property! Magic!! Sorcery, I say!
This line of reasoning is amazing.
