ABSTRACTWhile a reluctant European player now heading for the Exit, the UK was also an enthusiastic adopter of several key EU economic policies – namely, the skills and technology policies of Agenda 2020 and labour mobility. These initiatives worked with existing British policy, and structural biases, to exacerbate the already bifurcated structure of UK capitalism – between the high-paid technology and financial services sector on the one hand, and low-cost, low-wage sectors on the other hand. In particular, and central to the argument of this paper, immigration from Eastern and Central Europe after 2004 helped to sustain low-cost manufacturing and services industries by undermining firms’ incentives to invest in training. This combined with endemic failures in the UK’s skills system, which is heavily geared towards producing graduates with general skills but neglects the needs of mid and lower segments of the labour market. EU integration, therefore, exacerbated cleavages over skills between high- and low-productivity sectors and may have contributed to social divisions that led to Brexit.
