The major cause of modern crisis are the individual choices people have been making along history's course. Democracy allows people to choose their leaders, so if these leaders aren't performing as desired, why are people still voting and supporting them?
You can take any countries as example. People are constantly complaining about economical and social crisis, but at same time they defend politicians with enthusiasm, they idolize politicians.
Of course nothing will ever be fixed this way, because politicians feel safe to put in practice measures to benefit themselves, while neglecting the demands and needs of the population. There aren't negative consequences for them, so why would they change their actions?
How can the people choose their leaders when after voting the whole electoral process will be rigged and another leader will be chosen? The system has been fully manipulated. When the people vote those in power goes back inside and remove all the vote inserting their own vote. In my country last election i participated in voting. And these time i decided to keep record of all the votes in my local area and most importantly in my polling unit. When the result came out it was a whole different thing. The other candidate who have the least vote in local area was given the highest vote and he is our current president now.
