Daniel Klein analyses the differences in libertarian argumentation between challengers and bargainers using as an example the debate of raising the minimum wage. He talks about how there is no need to choose a side and it's fine to be at the same time a bargainer and a challenger. He also describes the delicate relationship between challengers and bargainers and how they can help to each another. Klein shares some galleries of famous libertarians who argued as challengers, bargainers and the third category: royalty.
