Do you think an advanced alien civilization would have a market economy?

Feudalism wasn't really a market economy, was it?

Possibly, but not in the form we'd know of. We can't assume such an economy - or any economy similar to ours is the standard for alien civilisations. You would assume not, as it appears extremely inefficient, wasteful and destructive. Which would mean they never attain the status of "advanced alien civilisation".

Like their biology, I doubt they will resemble us at all.

>Well, organisms have been competing for resources since the dawn of life.
We have once instance of this, we don't know what is common the universe if anything.

...

It will be a very advanced form of Communism as well as society that is highly pacifistic.

There is no other way to really achieve the whole "advanced civilization" thing.

Conservation of energy and thermodynamics makes scarcity an inevitability

Assuming they are smart enough to have figured out that a market-based economy is the most efficient economy, you would imagine so.

You would think a civilization built to support and spend resources on the genetically weakest, most inefficient, and sickest individuals wouldn't make it real far

Yes. Markets are the only thing aliens are guaranteed to have. They developed independently in every Earth culture.

It was a subsistence economy, which is what you get when population growth meets or exceeds economic growth. A market economy is what happens when economic growth exceeds population growth and is rare throughout history, occurring mostly in the last few hundred years as a result of the industrial revolution.

I tend to think if digital life is possible, a subsistence economy will return since copying digital persons will be cheap. Even if digital life isn't possible, humanity will hit a growth wall at some point due to fundamental growth limits (speed of light, etc.), so a subsistence future is still quite possible. A market economy is a sort of historic miracle, much as people hate markets. Any aliens we meet will be lucky to have retained something as comfortable as a market economy.

A lot of people in this thread seem to believe communism is likely, but again, coordination is hard. At the world scale, we can barely coordinate on ethical no-brainers like nuclear weapons or climate change. Doing so for interplanetary resource distribution seems difficult beyond belief, especially when attempts to do so within countries on our planet have ended in disaster. I will concede that anything is possible, though. Maybe there will be changes to the nature of intelligent beings so fundamental as to make them unrecognizable to us, and so any attempts to predict their future are for naught.
