The metric of per kg of product, while entirely fair, can be a bit misleading when it comes to making high impact decisions in your life. The switching to tea example is a good one to criticize because on this chart coffee is quite high up there, but I consume only 15g of coffee a day, compared to probably close to a kg of meat, egg, and dairy. Eliminating coffee would not be a high climate impact decision.
From your own source on "true" unemployment, it's the lowest it has been since they started calculating it. It peaked in 09 at 35% and again in COVID, but all through the early 00s it was between 28% and 30%.
You can't use that number as evidence we "already crashed", because as we've seen in other actual crashes it spikes up to 35%.
What about a masters in engineering and a bachelor's in chemistry makes him even double more qualified? Yeah, maybe if he had a doctorate you could make that argument, but you could easily learn and do as much science work in 6 years outside of a university than you would in a BS and MS program at a university.
Sounds like a strange dream I would have then wake up drooling on my pillow like a great dane.
