Those were rhetorical questions and it would be good for you to reflect upon them for a bit. Look up "negative externality" while you're at it, as this incredibly basic concept in economy seems to be entirely unfamiliar to you (as it is to many others, including those who like to play economists on the internet). Many things are "cheap for the consumer" while incredibly costly to the society and the ecosystem as a whole, and our entire society has been structured to shield the "consumer" (and most of the "producers") from having to think of the consequences of their actions.
The entire Western lifestyle is based on living on borrowed money. And we keep borrowing more and more, and the interest is compounding, and still people think it's somehow a sustainable way to live.
You're confusing bitterness with anger. I've been to therapy, and I've learned a few things. Including the fact that any competent therapist would say that it is okay to feel anger. That anger is an entirely justified emotion to feel about the sorry state of affairs that humanity has gotten itself and the planet into. That anger is an entirely justified emotion to feel on behalf of those who were given no choice on what kind of world to inherit.
But to be merely angry at the incredibly egoistic, self-obsessed people who revel in making things worse? No, that doesn't seem to fit. Try "disgusted" instead.

To paraphrase [1], "Yes, the planet got destroyed. But for a beautiful moment in time we created a lot of SUVs and 70" tellies for Western consumers."
The consumer at least. Probably the producer as well but I don't know as I'm not one.
Regarding your other paragraphs, you seem very bitter. Try therapy.
