Literally killdead argument is an argument that is a sure win in any discussion. I used it the other day in a video about strikes in Iceland (I'm becoming an internet star, something I will talk about in a later post). In Iceland inflation is the argument to end all arguments, if you are against any policy all you have to do is show that it will lead to inflation and the policy will be rejected, no matter how sensible it is otherwise (another Totschlagargument in Iceland is independence. In Germany, where we are less afraid of hyperinflation (because we do not try to maintain a currency with a population of 350.000) the Totschlagargument is "it will lose (or create) jobs", an argument that was used for all the new labour measures introduced in the 90s and any other kind of business friendly (and anti worker) policy. In both countries these arguments are regularly used to explain why the minimum wage cannot be a living wage.
