Not especially and not for the majority. Some risk it as they are likely to have family and a network that can support them. Make it easier for people to join families in the UK and you will likely reduce the number trying to cross and reduce the risk of 16 y/o’s drowning in the channel.
Most refugees stay in the first country they enter, meaning most of the pressure is on the Med countries. Turkey has over 2m refugees, mainly from Syria.
There are no votes in making it easier for refugees. You only have to remember the collective meltdown here and across Europe when Merkel gave 1m refugees safe harbour five years ago.
