Most conspiracies can be explained away as majority have zero proof. Government's story of 9/11 doesn't make sense, but that's the only one that I truly believe has more to it than meet the eye. They either allowed it or knew of it in advance. Many benefits came from 9/11 for various governments and for the economy.
Peak oil is a fact, and global over population is also a fact. The last century seen a exponential growth in knowledge and technology. We wouldn't have what we have today without oil and without fiat currency. Problem is that oil is finite and fiat currencies are based on debt. Due to cheap oil we are able to harvest massive amounts of food at a fraction of what it would cost us had we to do this by hand. To finance this technology we used fractional reserve banking which is great but there is also a limit to how far this can be stretched.
As humans we all want the best for us, and naturally we work in that direction. As we progress we use more finite resources and as societies we get deeper in debt. Even though, today the western world has everything they want, the developing world is trying to catch up. Problem is, the cheap oil has either peaked or we're very close to peaking. The global powers are also getting to the point where they will have to deal with debt and won't be able to push it off much further. Something will have to give.
Unless we shift to some alternative, safe and cheap fuels we will began to depend more on expensive oils in the near future which will affect human ability to harvest foods cheaply which will translate to higher food prices and problems with population in the third world countries and developing countries and finally us. Debt, again we are seeing hiccups around the world and at some point they won't be able to fix the debt problem and this exponential global growth just won't continue as it has been for a good long time.
Conspiracy theories make everything appear very simplistic when the problems are very complex. It's always easy to blame Politician A or B but the global picture isn't black and white and we are living in time where major change has to take place because the system as we know it is unsustainable. Can anyone imagine if half of human population lived like US does (in normal times not in recession)? How much natural resources would be used up each day? How much food would be wasted? How long would the world oil reserves last at that rate?
I think conspiracy theories are a big thing for many who began to awaken from wts, it's a stepping stone (even like E-watchman). I know I've taken that step, but as we move further away from wts ideology we also recognize that the world isn't as evil as potrayed but that many times people take wrong actions with good intentions. EU is a prime example. You can't fix major debt problem by forcing austerity measures and increasing debt load. It won't work for Greece, and it won't work for Spain under the system they have in place thus far. I think 1920s Germany is a good example of the outcome - one major difference with Euro states, is there is only one central bank for them all.
