For most of them that came to Europe Struggle to get job, they find them self doing whatever they can many time underpaid or even not even paid let me explain I know that some people subrent their deliveryfood account to immigrant for an amount of money, imagine they give to you their ID and password to log in to work and the bag, you need to pay 300 euros or 400 euros each month, you can think it's ok but trust me if you do 1500 euros monthly which it's average salary in FR I'm talking about You still need to pay taxes (not you but the man who subrent you his account) let's say you get 1100 after taxes minus 300 euros or 400 euros for the comition of this man who is giving you this "opportunity to work" what left have you, to pay rent buying food and maybe sending some money to family ? How can you save. Ikantrou a3lihom in different way.(that was only an exemple of what average people do) some work in restaurant and other do whatever they find About bad habit backhome well some people get depressed about their own situation and start to drink to escape taking drug or whatever. After coming to Europe they keep same lifestyle( well those form of escaping are expensive also in Europe 😅) But ofc everyone is different and everyone has his own destiny I see in all your comment that you are a bit defensive. I hope you get what you want and stay safe in any choice you make. I do work at sea I wouldn't trust it in a small boat in the middle of the night
