The world has always had problems. There is never any one thing (or three things) to blame. People will always find some thing or some one to blame. That's what led to World War II. Guess they were wrong there, huh?
We are part of the process. There are people, and perhaps you will be one of them, who think about these things in context and can offer rational, intelligent solutions or ways to deal with the immediate issues.
People who look for some one or some thing to blame are very short-sighted and usually only looking for their gain in the moment.
Think more broadly and just think about the role you play in the overall scheme of things. The Dark Ages lasted for almost 700 years before the dawn of the Renaissance. Somewhere throughout that period there were people who persevered and made that happen.
