You said they’re “trying to reduce prices for everyone” and you’re describing them trying to maximize prices for everyone (which, yes, they want to do).
[Edit: didn't pay enough attention to the flow of the conversation here - this is really a response to ProblemExplorer's original post, which linked to _diyar's post (parent to this one) as explanation].

No they did not. I am the grandparent and linked to their comment because they concisely explain how the airline made $150 off two sears instead of $100 while giving Bob the $50 deal he wanted (bay making Alice subsidize Bob).
If Alice used an MCP too, there would be no subsidy and neither Bob gets the $50 seat nor does Alice get her $100 seat
