And what is this so called cap on social contributions? Currently all employed pay the same percentage of their gross income for social contributions. The social cap would limit the contributions for social security. For the trade unions the limitation is the problem, as those earning more than the average would benefit from it.
Employers are convinced that companies who employ highly educated people are punished when it comes to taxes. The restriction would be valid for all those earning more than 37 thousand Euros gross per year.
In Europe 19 countries of the EU have introduced a cap on social contributions, Scandinavian countries - with the exception of Sweden and the Baltic States - do not have a cap on social contributions.
