It's wonderful to talk about airplanes landing, seats, and so on, but perhaps to simplify this a restaurant analogy is better.
You have a long lineup of people and a maître d'. You have people who are seated, and so many meals to be served. If the capacity was increased you could bring in more people, but I think the person who is the gatekeeper, the maître d', has to inform the people in the lineup, “If you stand in line at this point it's going to take you 15 minutes. If you stand in line at this point it's going to take you 20 minutes.”
Using standing in line for a restaurant as an analogy for how we manage the backlog, at some point we have to look at the input and how many meals we can prepare—in the context of a nation, how many settlements we can handle.
Do you not agree that we have to look at some controls in the lineup? We should be transparent to people and say “Look, it's going to take you seven years if you want to stand in the line”.
