There are many places on earth where travelling 4000 KM for a job will transform you into an immigrant with few rights but usually willing to accept unfavourable conditions because of difference in currency value between your home and the place you found work, basically hoping that a decade or so of hard work will help your family's future back home. There are also places on earth where you cannot easily get to another sufficiently richer country, so you don't even have the incentive to spare some money, just to go through the hard life of being an immigrant and then either adapt or come back with nothing. People do choose this options, do struggle for visas etc, but usually to do that you have to be strongly motivated. The system often is kept somewhat balanced by this, but this doesn't means it's favourable to workers/consumers.
