Unfortunately it's actually the opposite. The 90s and 2000s which had far less funding and popularity also coincided with a large amount of ambitious originals and OVAs. We can almost directly correlate the increasing popularity of the medium since 2015 and the decline of such originals in favour of cheap adaptations and remakes. The thing about all that extra funding is that most of it goes to the committee, not to the studios and animators working on it. And because the total manpower of the industry is so limited, that means that an excessive number of projects crowds out the labour that it becomes much harder to try out risky, experimental new things as one might have a decade ago. As the director of Code Geass stated; It would be literally impossible to air Code;Geass today. And the industry does suffer for it, because while there may have been many mega hits, they all largely lack lasting impressionns and fail to reach the legends of the past.
