This chapter draws together the main findings of the five case studies with regard to their arguments of economic victimisation and political marginalisation. It highlights how their rejection of solidarity with the rest of the parent state has mostly been based on the deservingness criteria of control, reciprocity and attitude. They have thus formulated a conditional conception of solidarity that, borrowing from Abts and Kochuyt (2013, 2014), it proposes to call ‘welfare producerism’ and, more specifically, a ‘culturalised’ form of welfare producerism. Furthermore, the case-study parties have used the transfers – oil revenues in Scotland’s case – as a ‘trump card’ to project the appealing and credible image of a more prosperous society combining competitiveness and welfare protection in a context of high international competition.
