For the benefit of GremlinUK, I think a short economics lesson is in order.
"Profit motive - a wonderful organising principal for an economy for the benefit of all."
Your statement - despite clearly being sarcastic when you wrote it - is actually perfectly true. Just look for an example at the 2 Germanys after the second world war. Both had the same raw materials to work with, yet one has a huge GDP, and both mean and median income are high; the other has a tiny GDP, and mean and median income is low. Why is this? Well, in any society, concentration of capital is key. Let's take an example, if I want to live in an apartment block, with my meagre capital, I'm unable to pay to build one, but I can combine capital with 100 other people and together we can afford to build one. That is capital concentration. In a state driven society, like a communist one, the only place where capital is concentrated is the state. If the state screws something up, they have a monopoly on capital, so they just go again, even if they have a history of screw-ups.
In a capitalist society, pretty much anyone can get there hands on capital. If I have a really good idea, and it makes sense, I can probably persuade someone (or some group of people) to give me seed capital, or even venture capital, either directly, or through stock market flotations. If I screw it up, I'll probably not get another chance, but if I'm really successful, people will start handing out money for bigger and bigger projects. Crucially, we get survival of the fittest, only those people with some sort of track record actually get the chance to keep doing big projects, so in general the big projects are done far more efficiently than in a state run enterprise. Now, the final part of this is that if I get rich from this effort, I want to do something with my money. What I do with it is invest in the stock-market - I become the person providing capital into the system. But, I pick and choose who I give capital to, so I perpetuate the Darwinian process.
Now, my final point in this is to ask you to consider a pound coin. How much is it worth? Well the answer depends on how many times it is used. If I spend it, then the person I give it to spends it, and so on, 100 times in a year, it is worth more than if it sits in my pocket for a year. This is why capitalist countries have higher standards of living, and high mean and median salaries. Crucially, imbalances in the amount of money we have are key to this process - try to remove them and the whole system starts to fail (look at the UK in the 70s with 98% top rate of tax).
For the record - I'm pro Microhoo!
