Very little of what you've said here makes any kind of sense. Your argument appears to be that during the 80's Japan was running on ill defined magic power which some how, in some unspecified manner, made their anime better in some unexplained manner.
Nonsense.
The ill-defined magic power was the bubble economy. They were flush with money and eager to spend it on luxuries, they were happy, they getting out into the world at large and competing and experiencing things and were perceived to be punching well above their weight. Japan was the second biggest economy in the world and absolutely dwarfed their traditional rivals China and Korea. The Economic Miracle of the sixties had not yet curdled into the Lost Decades. You can't discount the importance of zeitgeist here. Of course, it was all built on an unstable foundation that eventually collapsed, but it made for some really good anime and video games at the time.
The Japan of today has been wracked by twenty years of economic stagnation, has major demographic and quality of life issues related to that, China and South Korea are eating their lunch economically and in terms of international stature, and the people of the nation understandably aren't feeling as bullish as they were back in the '80s. They're turned far more inward in terms of their pursuits and ambitions. They're not having kids, their young adults are struggling to find work and establish households of their own, they're not spending as much money on luxuries and entertainment, and so those markets have come to be dominated by the few people who will continue to spend on expensive luxuries. In the case of anime, we're talking otaku. Unfortunately, a particular type of otaku.
I'm not saying that they can't still make good stuff today or that they don't. I'm just saying I think more of the stuff they made back then is stuff I would consider to be good or at least intriguing. I'm saying on average, the economic and cultural conditions that made anime such a breath of fresh air to the rest of the world in the '80s and '90s are no longer there. They make different, frankly cheaper stuff for a different internal market and that stuff appeals to fewer people here in their secondary, international market. (Plus, the West has taken no small influence from anime and manga and stepped up their game at the same time.) There is something different about the stuff they made back then, that's really all I'm saying.
