I'm not sure I buy that. There's not any proof that a more advanced civilization exists. Even if we assume that one does exist, why does it follow that they are immune to war, oppression, power struggles etc? The only data point we have suggests otherwise.

Or maybe the aliens are all holding hands in a circle singing kumbayah?

We have more data points in our imagination and it isn’t hard to imagine a more advanced peaceful civilisation.

Imagine you are an advanced civ with weapons hardly imaginable to current humans. Anti-Matter bombs, GRB strength energy weapons, etc, who even knows what is possible. With weapons like that even a run of the mill rogue political group, terrorist or whoever could probably trivially destroy an entire planet. It stands to reason that if they are able to continue to exist as some kind of multi-planetary species they have figured out a way to avoid killing themselves.

Nature often seems idyllic, when it has reached a stable equilibrium. But what it really is, is a ruthless and absolute class system, where each species "knows" its place, and has settled in to make the best of its lot.

The disruptions to equilibrium that we witness are almost always man-made. But there have been others, caused by new species, ice ages, asteriods, the Great Oxygenation Event, etc.

Alien civilization might be at equilibrium. Or, if we meet them, they may more likely be in an expansionist phase.

But I think a civilization that harnesses its conflicts - as we try to, with competing businesses, scientists, olitical parties, sporting teams - will have greater long-term success than a destructive, exploutative culture, by definition. It's not that competition is "good", but they we have aggressive aspects seeking dominance, and we are better off shaping them than having tribal warfare, raiding parties, etc which is more our natural state. And something like it is part of the nature of life itself.
