It’s not deflection, it’s exactly their point. In a healthy economy, inflation is low but positive, and the same or lower than the general increase in wages.
The US (and a bunch of other places) are currently having a hard time because inflation outran wage increases. In many countries, this is back under control (wages are now outpacing inflation) and we’re pretty quickly catching back up.
Part of the major problem in the US is the complete lack of regulation and unionisation. When we had similar inflation in Norway, our wage increases nearly matched the inflation, and the past two years, the wage increases have been very high compared to inflation in order to “recover”. When you don’t have any system in place to enforce this kind of response to inflation, it just leads to the owning class getting a larger share of the pie (what has happened in the US).
Do you have a source for this? My only reference here is hiking at > 10 000 ft (3000 m), and from that I can say that this seems very unlikely: If you stay at 3000 for a couple hours without acclimating first, you will definitely start to feel the effects. To be fair, you’re usually not moving around a lot in an aircraft, but a couple hours at 3000 m can make you feel sluggish and weak, and even a bit light-headed, you could even get a mild headache from oxygen deprivation.
Note that not everyone will see severe symptoms already at 3000 m. Plenty of people can go to 4000 m before seeing significant symptoms. However, given that I’ve never heard of anyone experiencing altitude sickness in a properly pressurised aircraft, it seems unlikely to me that they’re pressurised to 3000 m.
