Sure, but when one massive generation is the one in complete control when everything goes south, to deny their responsiblity is crazy. I don't blame everyone in the boomer generation for the state of the world today but everyone that I do blame for it does happen to be a boomer.
As I see it, its an opportunity for improvement. If the later generations fail to see the fault, and act to correct it - which, in the US anyway, is currently happening, then, IMO, the fault goes to the later generations for "continuing to do the same thing over and over and expecting different results."
Finally, though, someone has seen the futility of the matter and is acting to correct it. There's that old adage - "Hindsight is better than foresight" and I think it applies well. Unfortunately, what's done is done and at least the mistake is being owned and actions are being taken to correct it. The best that can be expected under the circumstances is what is being done - at least as I see it.
As I see it, it was Nixon who started it all. At the time, Mao Zedong was the Chinese.
For me, I see two missed opportunities for improvement in the resulting relationship between China and the US. The first is that trade between the US and China was significantly more normalized. As I understand it, the US did the same thing with Japan before WWII which likely lead to the Japanese being able to build up their military and return the favor to the US in the form of bombs. So the US entered better trade relations with China, and surprise, surprise, the US (and other countries likely as well) paid for it by making the US a shithole third-world nation with lowered standards of living and cheapass consumerism where products are crap to begin with and don't last long.
The second missed opportunity, at least as I see it, is that after centuries of isolation, Mao wanted China to be part of the modern world. IMO, the US First BS of the previous administration might well have lead to a similar condition if it prevailed and stuck. Though it did not go down that road, it is something that history has seen previously and it is known, if people take the time to examine it and think about it, that national isolation is not a good thing. Yet the previous administration wanted the US to try going down that road again whilst expecting better results. Humanity should know better - humans work better together.
