Failing Solidarity: Justified or Excused?

The concept of solidarity has been receiving growing attention from scholars in a wide range of disciplines. While this trend coincides with widespread unsuccessful attempts to achieve solidarity in the real world, the failure of solidarity as such remains a relatively unexplored topic. In the case of the so-called European Union (EU) refugee crisis, the fact that EU member states failed to fulfil their commitment to solidarity is now regarded as established wisdom. But as we try to come to terms with failing solidarity in the EU we are faced with a number of important questions: are all instances of failing solidarity equally morally reprehensible? Are some motivations for resorting to unsolidaristic measures more valid than others? What claims have an effective countervailing force against the commitment to act in solidarity?
