Yes. But that prosperity came with a massive balloon payment in the form of climate change. What's label prosperity today will be "Grand ma, WTF were y'all thinking?"
Long to short, the jury is still out on the actual success of Gen-X.
The climate has changed and will change. Some of that change (although I think its a small part) will be influenced by human activity. The Earth will adjust. Humanity will adjust. And humanity will continue to flourish.
A high percentage of the world's population lives on or near the coast. Why the climate is changing doesn't change the effect on these people and the places they live. Dismissing this fact as alarmist isn't going to help anyone.
p.s. Humanity will continue to flourish? Your prediction is based on what, past performance? When Mother Nature's bounty was harvested mindlesssly and shameleessly? That's going to continue forever? Infinitely? Can you share some links supporting such projections?
Long to short, the jury is still out on the actual success of Gen-X.
