@betazed, What a great discussion. V enjoyable. Do you really get to do this for a living, I'm so jealous.

Are you lost because I was not clear or because you do not agree?
In case I was not clear let me elaborate. Growth (creation of wealth) requires investment. Growing 10% from $100 economy to $110 economy requires $50 in excess investment and can be done in 1 year (say). Then most probably unless we see a quantum leap in technology (which comes once in a while) growth from $1000 to $1100 will take more than $50 in investment and more than 1 year. So as we grow our investment time span and investment amount increases monotonically. at some point of time it will be more than the critical period of vision of capitalistic ventures. Then these investments will not take place and growth will be halted.
In case you do not agree, I would like to know why.
OK, I'm not sure that I really understand this. In the previous post you argued that giganitc engineering projects were necessary to keep capitalism growing, that's the point where you lost me, because it wasn't self evident to me that that was the case.
There is a problem with time horizons and I completely agree with you on it. But I don't see why it necessarily causes growth to stop. Do you have a reason for thinking that the time horizons to achieve a positive return of available investment projects is getting longer? My guess would be that it wasn't, but if you have some reason, please say.
Why do I say it isn't? Well one thing is that interest rates (at all maturities) are much lower than 20 years ago, so the rate of return required from that point of view will be lower.
Also I don't believe that there is just a finite number of investment opportunities and the best ones get exhausted so the remaining ones have a longer time horizon. Instead I think that the available projects increases with technological progress.

Are we sure of that? yes, we do not need them now for growth now (maybe, although I can probably argue we do). But what about in another hundred years? we will need them then. We need to reach space economically to expand and have access to more resources. We need to clean up our planet because we cannot pollute it continuously. We need to alleviate the poverty of so many people because otherwise we will never rid ourselves of political troubles and extremism. But these projects will take decades to acheive. If we need them desperately enough to be willing to invest in them in a hundred years or so then decide to start them, we might be in a jam for the decades it will take to finish them (and we may not be able to finish them at all then because we may be in a fix)!
Look, first of all let me say that the 5 projects you outlined in the previous post are desirable, but only the 5th I think is truly necessary for medium to long term economic growth.
As you've pointed out earlier in the thread economic growth is not dependent on ever increasing amounts of resources being available.
I agree that pollution is undesirable, but it is not clear to me that low level pollution really will bring catastrophe (by this I mean, for example that I think that while we might have moral qualms about it, dumping waste in the deep sea will not store up long term economic problems for us). Another problem is that people disagree on its nature. In Britain at the moment there's a big debate about whether wind farms are good or bad for the environment.
I can't think of a more desirable use for the world's resources than alleviating some of the extreme poverty that we see today. However, I've recently reversed my opinion that it is a cause of political extremism. Look at the Sep 11th hijackers, they were not the economically dispossesed. They were well educated with economic opportunities (they'd gone to live in the US even) so I don't think a side effect of reducing poverty will be reducing extremism. I have views on how that should be done, but that is for another thread.

The specifics of consumption and technology and growth maybe unpredictable. But overall trends of growth are not. We know that we want to be growing in the year 2050, in 2150 and even in 2250. We know that we will need more and more energy. We know that the population will hit 8-10 billion. Similarly, overall problems of growth are also not unpredictable. We know that US consumption is not sustainable. We know that poverty should be alleviated. We know that fossil fuels pollute. We know all these things, yet owing to short sighted capitalism we will not take actions to tackle these problems.
I am not saying that we need to predict the future in all its gory details. As Yogi Berra famously said "Prediction is difficult, especially about the future". But we need to understand the consequences of present actions and correct our trends. That is not too hard to fathom.
Agreed.
There is a problem with private property and private returns. If you think about a big infrastructure project (like the sort of the ones you are describing) the benefits will be shared out among many different agents. But capitalist development requires that the agent who builds it gets back from the project more than they invest in it. It's a classic public good problem, of the sort I'm sure you are familiar with.
For others, the problem is something like this. In my street there are 5 households and no street light. Having a streetlight would be worth $10 to me, and worth $10 to each of the other 4 houses. However, a street light costs $25, thus it is not worth it for me to buy, nor for any other given household to buy. Thus if we rely completely on private property with returns going to one agent, the streetlight will never get built, even though as a group we'd get back more from it than we would have to put in.
A most unfortunate side effect of the West's apparent victory in the cold war (although it isn't down entirely to this) has been the elevation of the principle of private ownership of property to a level where it prevents desirable collective action being taken through an institution set up for the purpose of taking desirable collective action, namely the Government. When desirable societal benefits accrue, but a specific investment project by a private agent would not yield a sufficient return TO THAT AGENT to make the project worthwhile, the government should be intervening.

Now, if a internal problem of something leads to its own demise then won't you call it an inconsistency? Maybe, maybe not. But that will be an argument in semantics.
Sorry, I didn't want to sound like is was making a smart-alec comment, what I meant was that despite agreeing with you about some of the problems facing capitalism, I'm not yet sufficiently convinced that they will lead to capitalisms demise.
