Ten years ago, on 15 September 2008, the US investment bank Lehman Brothers collapsed. This collapse is largely seen as a key event of the North Atlantic financial crisis, which also had spillover effects on the rest of the world. Around the globe, this decade-long crisis has caused massive unemployment, as well as rising poverty and inequality. It has been used and abused to slash people’s rights – in particular the rights of workers – while the financial sector that caused the crisis has benefited from huge publicly funded bailouts. Ten years after the last crisis began, global debt levels are higher than before, and debt vulnerabilities are increasingly hard to manage. That’s why activists all over the world are standing up to call for fundamental reforms of the financial sector on 15 September 2018.
