I am currently obsessed with financial literacy/illiteracy and the complexity of the financial system - not just at a large/corporate level, but also for personal finances and pretty much any aspect of our lives that incorporates financial products. It's crazy how that complexity blurs the reality of what is offered to us and makes it extremely hard to make good decisions, and how much of an overhead it adds to going through everyday life.
It obsesses me, and hence drives a lot of what I read, watch or do on my free time, hence you could say that it drives me !
