Aside from a little extra effort in manufacturing, I fail to see it.
Jetting everywhere for the sake of it, yes, this is worth critizicing( and mocking), but a golden luxory is harmless I think and not worth a class warfare.
Somebody focusing so much on status so as to need to spend this much money is merely out of my understanding. Yes, it's some form of intolerance on my side and I fully admit it.
Now, gold is both rare and needed, and implies mining, and possibly underpaid people with awful work conditions. I find building such short-lived and futile items with it irresponsible. It's fortunate it's mostly anecdotal. But these people are so out of touch with the realities of our world. This is what, among other things, I see in a gold watch.
Showing status is a double edged sword.
Of course, it works both ways. Someone wearing a gold watch probably wouldn't care for me. At least the relation is likely symmetrical.
Out of mine either. But I accept that other people have other values and rather focus on the things in common. In this case, fighting for things to last.
They are already the decision makers not taking the right decisions for the environment. They are the ones choosing not to be on my side.
We need to spend a lot of efforts fighting their carelessness and bad decision-making. I want to be able to mock them. (though I don't usually do it, it does not bring joy in me, mostly bitterness).
If someone rich is reading my comment and taking issue with it, they need to treat the cause and stop the dissonance. I don't expect rich people already doing something for the environment to take issue with it.
