The middle-class base of European integration? New class divides and attitudes towards market integration in ten EU countries

Highly educated ‘new’ middle classes have been identified as a fundamental constituency that, by supporting technological innovation and liberalisation, bolsters the stability of advanced capitalism. By contrast, less educated production workers are usually described as opponents of such policies. This article investigates the extent to which these class divides translate into different positions on support for EU integration, a key process in the liberalisation of European political economy. In addition to class-based positions, we take into consideration how the subjective perceptions of situations such as unemployment, income loss and job insecurity affect support for EU integration. By relying on an original 2019 survey conducted in ten member states, the analysis confirms that high-skilled middle classes overwhelmingly support European market integration, while ‘old’ middle classes appear more concerned about the welfare losses that integration could imply. Low-skilled service workers emerge as a critical cross-pressured group, taking a mid position between ‘old’ and ‘new’ middle classes.
