The third theory that aims at explaining the matter of interest focuses on the actors rather than abstract notions and generalizations. The supporters of this theory believe that these actors are groups of people, which claim to represent economic classes, such as trade and labor unions.17 The theory is beneficial for explaining the differences in welfare state regimes, as there is no guarantee that such groups would emerge or they would have the same powers or structures in different societies.18 According to the theory, the emergence of welfare states is the result of political reaction to the rivalry between different classes, which may also vary depending on societies' beliefs and presumptions.19 The classes unite in coalitions and have varying demands, which results in three different types of welfare capitalism.20 While the theory seems well-rounded, there is another approach that provides a comprehensive explanation of the emergence of welfare states.
