Sadly, this would probably not go well in Congress - not only are most of the members of Congress not particularly good at speaking and getting points across in general, those that are tend to slip into dumb political gestures rather than sticking to substantive policy ideas. But it would be nice to see a member of Congress or the Senate (I don't care which side) take a similar slap at what's happening right now in this country, which is heading down almost as fast as the UK under similar policies.
Best line: "The truth, Prime Minister, is that you have run out of our money."
I enjoyed the point that every British child is born into about 20,000 pounds of debt; in the USA, children today are born with $22,000~ of debt, plus whatever the interest costs. It's astounding.
