Perfection is on an infinitum, so there can be a small chance of arriving at something, but there are good steps. There would be social programs to meet everyone's needs to live, no one in the world would have to starve, go thirsty, live on the streets, or not have healthcare. An end to racism and an acceptance of all LGBT+ people, or at least a social understanding that it is not cool to be racist/homophobic/transphobic. Put an end to sexism also, need an end to discrimination to all genders, of course being non-binary is accepted as identities as defying social norms for genders is also accepted, and puberty blockers available before puberty. Some flawless technology to help people be their best selves would also be nice, that means trans people could have their desired reproductive ability, but this also means many cis people who would otherwise be infertile can regain their ability, and many other things for disabled people.
Acceptance of neurodivergent people also, with a history of things being studied so that the needs of people can be met. Minimal to no use of fossil fuels, perhaps a transition to energy sources that are not so catastrophic to the planet and finite, before entirely renewable. Nature preserves are well kept in ways that secure the natural habitats for animals, we are not going into the habitats of the animals to cut down trees and destroy these ancient ecosystems, we would need to somehow have reversed the acidification of coral reefs also, something being caused by climate change.
The entertainment industry is competitive and is open to creativity to many different creators/companies, with sensible copyright law that does not continuously get extended instead of entering the public domain like it has become. Employment is accessible to everyone who wishes to have it, whether to make your ideas interesting, wanting to make things better, or more resources for something you might want, it is there. Class is broken down, so those born into wealth don't just inherit that power themselves, as those born in poverty are not at major disadvantages.
That is what I can think of so far.
