That might be why Gamora works and Captain Marvel doesn't, because of human(?) connections.
She starts out the film as a lone vigilante trying to keep the infinity stone out of Thanos' hands, is willing to harm or even kill people to do so if needed, but realizes she needs help from the others to accomplish this goal. She threatens to kill Starlord for putting moves on her and is just generally uncooperative for most of her scenes but slowly starts to trust and appreciate them.
Captain Marvel is the opposite development: She's got a bunch of space nazi friends who do bad things together and she has no idea because of her space-magic amnesia. She communicates with the earthlings but mostly at gunpoint or under similar threat, except for the singular living woman who knows her past, and then when she discovers her powers she just goes and finishes everything on her own with 0 struggle or hesitation. It's the extremist teenage power fantasy: become a complete recluse and kill everyone who looks at you funny.
Then there as never been in the history of this earth a shining beacon of success because at every waking moment there wasn't an optimal number of people immune to all disease, death, and suffering, to no downside to nature around them?
The 90s is where the curve peaked for a lot of people. China had finished bringing 70% of their population out of extreme poverty since the world war era, the USA markets and deficit were stable though heading in a bad direction due to Reagan, and Europe was having a big cultural and tourism boom.
