This can be said of literally anyone living in the first World.

I find it deeply laughable anyone would stand on a soap box who lives in a modern first world environment and lecture like this while not seeing the irony that they do it themselves at their level as well.

Please. Stop. Look around. And maybe visit a place where you see how the other half of the planet lives. Likely your world is wildly ostentatious and unnecessary comparatively.

The plank in your eye before your neighbor and all that.
