Refugee runs away from, economic migrant goes abroad to.
If I'm not mistaken, Isn't this a trend from other European countries too like Romania and Serbia/Belarus?
I would say there isn't. If your economic situation is so bad, that you are willing to throw yourself into the sea on a rubber dinghy, you are a refugee from severe poverty and life so horrible that you are willing to risk dying just to escape it.
If it was up to me, I would expand charter of human rights to include this.
Only if the host country has the right to demand for them to leave their culture, religion and customs at the door. Otherwise it could be a very bad deal for the welcoming country.
You are not entitled to a better life somewhere else, other than the country you are citizen of.
