Earlier quoted context omitted.
You might notice that these quotes talk about the future. That's literally the point. They see a development and realize that they'll have a problem if the status quo is kept the same. It won't, which is why the actual issue mostly fails to realize as projected.
>it won’t That’s the core disagreement. It’s like when a car is driving with 200mph toward a brick wall and you say “I don’t understand why they panic, the car will stop doing that before hitting the wall”. Sure, that’s a possibility. But I understand projecting a current trajectory in trying to prepare for the future.
I disagree, it's more like you're in a tank and have been running over every obstacle in the way, with someone on the side constantly shouting "new next one is going to destroy your tank". It's obviously possible, but considering how little we're already valuing labor and have been in a phase of adding even more entirely pointless jobs because the labor is cheap and available - I honestly do believe that I'd be a very healthy thing for our societies to downsize (numerically) again. At least to pre world war 1 levels.
It's obviously not going to be easy, but this whole system is going to go bust anyway once the millennials get too old to work, immigration at best postpones this issue for a few years while introducing a shitton of new ones to the equation.
There is no perfect solution, but immigration is one of the worst for this particular problem
