MMW, there will not be a viable colony on Mars within the lifetime of anyone reading this. They might get there, they might try, but they will not survive for long.

Every week the wealthiest person must be sacrificed to our lord and savior Mars.

In the event that multiple people have the same amount of wealth they all must be sacrificed.

Also, shell companies are punishable by death. Helping the wealthy hide their wealth is also punishable by death.

Forbes Mars is pretty much a list of godly sacrifices.

Self-sufficient one? Probably not, but why wouldn't they survive for long?

God no! Everyone knows your can't use a direct monetary value, you have to tie it to something that scales with inflation or eventually the poors can get in.

I thought this was a picture of a pizza from the thumbnail and I am disappointed now.

All resources are shared equally, to ensure that everyone is provided for.

The Native Martians, obviously.

No kings.

I guess the most fundamental 2 things is climate change, and the societal upheaval likely to result from certain modern technologies.

By climate change, I include patterns in economies, food security, water, migration, wars over resources, population/demographics, public health... that have already started but clearly will intensify.

For technology, I've heard that after the widespread use of the printing press, or the industrial revolution, there were big turbulent changes in society that lasted a century. Some people reckon the modern internet/social media was another such disruptor, and I do agree you can trace a lot of "post-truth", loss of trust in institutions, etc, back to that. AI could make this worse too.

Then, most traditionally rich countries are facing demographic trouble and national debt.

It's not clear how it'll all shake out or when, but it's difficult to see many players being able to afford regular supply missions to Mars in the next phase... lifetimes of people currently alive... we're likely to see less progress than we're used to.

I kind of like how the society is structured in Kim Stanley Robinson's Blue Mars

I read that series a long time ago and loved it.

What do you like about the blue Mars social structure?

It's just really utopian and socialist and like hopeful and stuff :3

We are going with both legs into ww3 and there is a chance that it will take us (as in humanity) into a mess for a decade or two, but rich nations wouldn't desintegrate nor would they collapse due to climate change.

It depends on what kind of a martian colony we are going to get (probably we won't get any) if it's a vanity project of crazy billionaire it's one thing, another thing if there is an actual need for such a colony.

I remember a lot of long distance running, and some group sex where one person was the focus for everyone else to pleasure (if I ever write a sci-fi, I won't put any sexy bits in it... always seems to age fast, and seems weird and dated after...[maybe that's just me tho]).

Ok.

Love your optimism about rich nations not disintegrating. The way I see climate change happening, there's soon major changes in weather/ rainfall. Also some ecological collapse (eg bees, other pollinators, ocean acidification), with knock on effects to agriculture. Even problems in other parts of the world create pressure for resources, wars, increased migration....
Too much to detail, but many things that come to a breaking point in the next decades.

I'd love to hear why you think this seems unlikely. Look at the end of the roman empire. Or any empire. Things don't stay the same just because.

Yeah, there were a bunch if tangents and it was a bit rambly, but I did actually like the sex positive nature of it, I think it would have to be there for a utopia to exist :p

Also advanced medicine and body changing and more relaxed social norms around nudity and stuff... it was kind of like a breath of fresh air to read a positive sci fi novel I think!

If you can’t find the clit right away, lick the booty hole.

Hypocrisy is the main sin. If you proclaim one thing and do the other you get ostracized.

Fare from Mars back to Earth should always be free.

What kind of sacrifice we talking? Like railgun them into space? Maybe throw them off Olympus mons?

Could go the Futurama route: https://youtu.be/0kJEX5GTxJc

US empire is dying, but it's not even close to instability that plagued rome for centuries.
Part of roman empire ended due to many factors (including climate change) but they were pretty powerless by the end, where rich nations now aren't and have resources to enforce their position. I'm not saying that they won't feel the pressure and their living standards won't suffer at least temporarily.
Everything else is reversible or can be mitigated.

Make it a threshold, percentage based. If the richest person is worth over 3x what the poorest one makes then axe ‘em. If that extra value has to go somewhere other than a person it goes towards the community. Yea, you can have assets that are worth way more than 3x but, oh, guess those are actually public now and not yours alone.

Shhh! Let all the Musks and Bezos et similia go there, try, and die in hilariously dumb ways.

Let’s do it right and put the rabbits in charge this time.

I could see musk trying to make a spaceship out of submarine material.

It should cost $20M and be free for anyone with a net worth under $20M, with the caveat that anyone with a net worth over $20M must pay a surcharge of $100 Quadrillion in some inflation proof assets (I have to do work instead of hyperfocus on this further). If they can’t pay it, too bad.
