I've uploaded it in five parts onto Youtube (because there is a 15 minute limit on the duration of a video).
Part one asks what an optimal tax system would look like, and looks at the history of idea that you could replace the existing tax system with a flat rate financial transaction tax. You can either click on the video directly on this page or click here to go directly to the Youtube site.
I hope you like them. I'm actually quite pleased with them, even though there are moments when my fluency leaves a little to be desired. I'm really pleased with the software that I used to combine the video with the Keynote presentation - It's called ScreenFlow in case you are interested.
Do feel free to comment. And don't hesitate to let others know about these videos. My next step is to do another set of videos in French! Stay tuned...
