There is a makeshift refugee camp in the French town of Calais full of Afghans, Pakistanis, Eritreans, Sudanese who refuse to claim asylum in France and want to illegally hop on lorries heading for the eurotunnel to the UK. This is super weird to me. What makes France so unappealing to these people?
Late answer sorry, it's a well documented issue in social sciences in France (if you can read French). There are basically 3 points:
1. In the UK (just like in the US) you don't have an ID card system (carte d'identité) with police randomly controlling you to check if you're illegal or not. The UK and North America are harder to get in but once you're in it, your chance to get deported will be pretty low. These migrants know that if they stay in continental Europe it may be hard for them to stay.
2. Illegal work: the "pragmatic" Brit government and economy are less controlling about illegal employment than in France. These guys will then be able to make money faster.
3. The diaspora and connections: most of the migrants in Calais come from Somali/Sudan/Afghanistan and they already have relatives/contacts in England that will help them for housing and working (look documentaries about the topic, these guys have sometimes 2/3 phones to keep in touch with the UK). They have nobody in France…
France actually used to be more generous about asylum policies for decades but I guess they don't care since their goal is to join their network in England. It's probably the same reasons why Turks want to go to Germany/Netherlands, and Africans/Arabs go to France.
