From time to time, there will be xenophobic attacks because of this problem and scores of illegal immigrants will be killed. For over 10 years now, the problem is still there and no political will to solve it. In turn, we decided to make our borders porous. Allowing them to get in. We do deport them from time to time, only for them to come back. Problem is that not every illegal immigrant is here to work for peanuts. Some come to conduct the business of crime. Which is a bigger problem than someone stealing jobs locals aren't interested in doing.
I am starting to believe that the whole capitalism system thrives on slavery of some sort. Cheap labour results in good profit.
