It's much much deeper then North/South, Banks, UK, US, Politics, EU, etc. Our everyday lives are busy so who follows all this complicated shit they can't control? I do because I make money from it and when learning the true realities, the ignorant are truly blessed.
Anyway, the main problem:
The word "derivatives" simply means a bet has been made. Originally, these bets were designed to hedge/cover risk. Nine of the largest banks in the US total more than $200 trillion of
exposure to derivatives. If the derivatives ever showed signs of weakness it would completely collapse and there isn't enough money in the world to fix it. Again, this is "just" the US and not the the rest of the world, but today the worldwide derivatives market ballooned, estimated between $600 trillion to $1.5 quadrillion.
The world's GDP is only $65 trillion comparatively so again, it's not about political leaders or euro/dollar or fucking Greece. It's only about speculation, confidence, and exposure. The ECB and FED can't print/pump enough money into the system because once it goes, TOTAL failure because the exposure is just too great.
