I'm not an economist and don't pretend to be one.
I've heard about huge US national debt and now thought about it for a moment.
So with current US national debt as 12 trillion and
£796.9 billion of UK national debt (55.5% of GDP) it has a sense to call that 2 major Western society countries are not self-sustainable.
Americans and British consume way more than they produce and can't feed themselves on its own, only by others.
So all that democratic principles on which Western society is built as we know it now is a total bullshit, because it's doomed. And all we live in illusive world on a global scale. If any system declines for a long time in such huge scale, one day it'll fail and crush. What will be instead of it? Fuck, why nobody is thinking about any vital society model, at least there's nothing about it on the news.
