I agree that the real power is in the hands of the people. You only need a minority the overthrow the government, but that is becoming increasingly difficult and very dangerous. This minority seems to be getting smaller, depending on your location.
For the EU, e. g., I see that as a lost cause. It's being destroyed on all sides, all citizens will be taxed into oblivion, pensions robbed, blocking capital from moving it outside the EU and in the end preventing citizens from leaving the EU. That is how I see EU's downfall. You van try to "fix" or do some stuff, but it would not matter. Protecting your capital and your freedom by leaving is the best option I see.
