George Soros knows a lot about financial systems. Strong evidence is the fact that he's rich and shares his perspectives, which are better than mainstream perspectives at interpreting market behavior particularly during major crises. My favourite quote of his is the oft-repeated notion that Classical economics is based on a false analogy with Newtonian physics. He generally spends some time either side of that comment making it really clear: there is no mystical market equilibrium of supply and demand, only the behavior of individuals.
