Every week, John Oliver tackles an issue that has been appearing in the news, and cuts through all the faff to point out that a lot of what's reported about it can be pretty selective.

He then connects the dots, with a dose of humour, that helps to make what can be complex and complicated issues be understood a bit better. He's already given FIFA a right roasting, looked at Uganada's worrying anti-gay laws and this week he decides to tackle the income gap in America. 

It has always been a part of the 'American Dream' that you should be able to rise from the bottom to the top, but with a worryingly widening gap, the likes of which hasn't been seen since the 1920s, it's time to start doing something. Oliver explains exactly why we should be concerned, using lottery balls and a reference to Downton Abbey, of course.
