Aegean mystery

What is our (i.e. Europe's) policy on migrants coming from Turkey?  Every day seems to bring stories of boats packed with migrants capsizing with loss of life.  And yet, we send ships out to try and find these boats and take their passengers on board and bring them safely to Greece - where they were trying to get to anyway.  So if we're doing that, why not simply provide an official ferry service between Turkey and Greece?  Why force them to put their lives at risk when, if we pick them up, we will help them complete their journey.  Am I missing something?
