re: a further point
The problem is you don't understand how any left wing economics actually works and so you dismiss it as irrelevant. All systems vary between randomness and chaos, which is another way of saying they vary between independant actions (randomness and probability) and dependant actions (chaos and catastrophe theory).
Chaos is fundamentally complex and can't be simplified. All this right wing propaganda that capitalism somehow won some kind of contest with socialism is just nonsense. The two kinds of phenomena happen side by side and the only way to run an economy efficiently is to maximise the understanding of both mathematically.
Ignoring chaos gives you something like Bush, with perhaps the worst economic management since Hoover.
