Is that really the world we live in? Have you met rational humans? Are we living in ideal markets?

Truth is, bad situations of all sorts are springing up and remaining in place long-term. A closer look at each individual issue (as done in this thread) reveals complex factors that need to be adressed. Using a simplistic model from economics to ignore any and all ethics (term used loosely for any attempt to do what's right) is not valid imo.
