I think you can be a realist and still be an optimist. If the house has an unstable foundation and the beams are rotten and the facade is hanging by a thread, the optimist will tear it down and build anew. Where is the comfort in pretending the house is sturdy when the next storm is sure to blow it down..... as you often refer to creative destruction, you must then understand that the boom is the disease and the bust is the cure....
