So you can trust the economist's too. Also "wanting more trees" is something you can measure, it is not a feeling. Asking them if there are enough trees in their city and comparing them with another, unrelated sample taken from a different place instead is throwing numbers around and doesn't tell you which city has enough trees.

That's a pretty good example I'd say. It's normal practice for most countries out there. I'd even say that as long as you have borders you'll find someone who wants to push them further.
No, that's not how it works. If you test something thatbis not even scientifically measurable over two different samples you aren't testing shit. You are just throwing numbers around that don't correlate to each other.
