Capitalism is the least worse option, to coin a phrase. The notion of a market economy has its faults but it has consistently proved the model by which supply and demand works its way through and allows surpluses to be created.

The issue we have at the moment is effectively the influence of both corporations and the petro-dollar. The later will, I expect, be negated by technology and Corporations will effectively implode on themselves in the way that they always do.

What follows, then I do not know but outside of some world in which the primary driver of market forces is eliminated i.e scarcity, then a market economy, and the subsequent capitalism it creates, will be with us in one form or the other. Any attempts to crush it through other means invariably ends in failure.

And let's not forget that despite all the current worries and woes, we are still living longer (and not sure that is a good thing but bringing personal issues to the table on that one) on average than any human before and the global increase in living standards over the last 100 years is unprecedented.

I saw the title and thought of Swiss "end of life" clinics making too much from their captive client base.

I'd be more immediately concerned about food getting expensive. I think the thread has an interesting premise - people should take a look at what Marx and Engels actually said, rather than listen to US anti communist propaganda.
I'm trying to recall the exact thesis but it was a long the lines of:
Capitalism goes in boom bust cycles - high prices/ low prices speculation profit to be made.
The boom bust cycles get closer and closer together and more frequent - less and less people are satisfied by the system.
The common people, not really owning anything (the proletariat) realise the problem (become class conscious) and take everything from the bourgeoisie (the people with property/capital).
They didn't say people should do it, or that it is good, or nice. They just said it was basically inevitable.
I can't help but think in a global world, we could be looking at a new world system starting to emerge in our time. America and NATO seemed so great up to the 90s. Now - the gloss has worn off and we can visibly see the decline.
