If you’re wondering how the global economy got in the state it’s currently in, you need look no further than the National Debt Clock in Times Square, new York.

This clock has been measuring national debt since 1989, when it was at $2.7 trillion. It’s now at over $10 trillion, meaning the clock needs an extra digit adding.

So, in the last 20 years, people in the US have borrowed almost $7 trillion. I’m guessing that’s got something to do with why we’re all screwed right now.

What’s disconcerting is that rather than just adding one digit to the clock, they’re going to add two, meaning it can track up to a quadrillion dollars of debt: a number so huge, I can’t even comprehend it.
