I lived in the middle east and quite a few of my DC’s arab friends had been born in the USA or Canada. Their parents often had to travel and stay in the country months ahead of the birth to not be turned away from the border. All well educated people who were keenly aware of the advantages of a western passport. They weren’t in desperate straits or anything but it was seen as better for the children to be able to move freely to those countries or even just never living there but having the right passport. The difference is they had some money.
I think people have to bear in mind that economic instability or the environment in many countries makes even the crappiest area in the Uk look very attractive. I do think it’s driven by economic opportunity and most people just want better lives. There is zero chance that most have the skills that would get them a visa.
I was watching a documentary about people who had returned because they didn’t make it to the countries they had been aiming for (it was an african country can’t remember which). Many had basically lost family money (families would put the money together to send them) and were shunned, they all wanted to leave because they were skint not because of anything else. I completely get that, I’m from an immigrant family myself and just living in the west can change the entire direction of your family’s life, both your nuclear one and the family in your country of origin.
There are also people genuinely escaping specific threats from their own governments, some afghans, Iranians, Syrians, theres a Palestinian guy who had to get out of Gaza because he campaigned against Hamas. So there are people fleeing genuine persecution and are at very real risk of torture and murder. But I don’t think they are the majority.
I have all the sympathy in the world for someone who just wants their life to be better, we all generally want that. Most are young men who believe they are immortal, so even if they see boats sinking they don’t think it can possibly happen to them. Also you can see england from france, it probably doesn’t look like it could be that dangerous. I think traffickers lie, I think they tell them that they aren’t like the other traffickers and that their boat is safe. And once you are standing on that beach and spent thousands of pounds you have collected from your extended family or loans and you are so close, you are unlikely to say “no that doesn’t look safe” while some demented bastard is yelling at you and waving a gun.
