Much of the phenomenon of labour-market polarisation can be traced to macroeconomic trends and structural changes in sectors. The rising supply of non-national workers is also a factor in this, while technological and task content changes seem to play a minor role.
In light of the continuous shift towards a tertiary-based economy, together with the predictable changes in consumption models and lifestyle of European societies, it is likely that a relative increase of elementary occupation is bound to persist also in the next future. However specific policies, including vocational education and training, could potentially favour a process of occupational upgrading in the future, reducing the polarisation trend.
