At the end of the ad, they ask you whether the Robin Hood tax is a good idea or not; feel free to answer - though perhaps you should first read the information about this tax in the paragraph below the video.
This video is an ad (= advert, advertisement) paid by The Robin Hood Tax. The Robin Hood Tax campaign is a movement bringing together dozens of organisations (such as Greenpeace, Water Aid, Unicef, Oxfam, Comic Relief...) that work to reduce poverty in the UK and overseas, and campaign to tackle climate change. They have come together during the economic crisis to campaign for a new deal between banks and society. In fact, their motto is "turning a crisis for the banks into an opportunity for the world" and this campaign works to impose a "Robin Hood tax" on banks´transactions.
Sure you have all heard about Robin Hood but this link will take you to a webpage written by a lover of this story which will show you lots of different sides of the story.
If you liked this ad and you would like to see "The Banker 1", click here. The dialogues are much longer, though, and it´s considerably more difficult to understand.
