<s>[INST] The next text is a question of a member of the European parliament:"The Danish newspaper Jyske Vestkysten reported on 15 March that a businessman from Kiel had had the idea of supplying German workers to Danish firms. This is a shrewd idea in that the German government subsidises German workers who take up jobs abroad by approximately DKK 60 an hour. The individual worker also receives a tax allowance of some DKK 800 a day.  The businessman in question has sent 3 000 e-mails and faxes to Danish firms offering to supply them with German workers in the building trades at an hourly rate of DKK 120. By way of comparison, a firm must pay between DKK 175 and 190 an hour for a skilled Danish worker.  The businessman is doing nothing illegal, he is simply exploiting current German law as the system was introduced by the Federal Institute of Labour. However, this system is severely undermining the Danish labour market in that it is increasing the pressure on a sector in which unemployment is currently rising.  Germany has, in effect, introduced an unfair system in an attempt to export high German unemployment to another Member State, in this case Denmark, thereby undermining the Danish system.  In the light of this situation, what does the Commission intend to do to put an end to this arrangement, which is distorting competition?"
