Social Union, Convergence and Migration

The forces of the market and systems competition bring about
economic and social convergence in Europe, and there is no need for
social policies at the EU level. Social harmonization would distort
migration flows and slow down the speed of economic convergence.
National welfare states will be threatened by the free migration of
people in Europe. The race to the bottom is a serious risk.
However, to contain this risk, neither harmonization of welfare
payments nor constraints on migration are needed. The adoption of
the principle of selectively delayed integration is a better
alternative.
