The article in the DM was inflammatory, designed to encourage hostility rather than compassion. Migration from one place to another is what has driven humanity and made us who we are. This is not something that we can make "go away" by draconian measures or by encouraging hatred. If you were born in a stable country with a developed economy, you got very lucky.
We now spend a third of our overseas development money which was cut (in 2021, I think) in the UK supporting migrants. Surely, if we want to reduce the numbers of people desperate for better lives, it would be better to help them in their own countries rather than in the UK? People don't leave their families, walk across deserts, live in camps, get in unsafe boats etc because they are going on holiday. They do it because they and their families are starving or in fear of their lives. I would do it too if I had to but fortunately I got the gold star when I was born!
My GGD worked in the mines all of his life at 72 he and his 10 year old GS walked to Manchester to dig the Manchester ship canal because there was no work available where he lived. They would have been seen as filthy itinerants, sleeping under hedges and relying on the kindness of strangers. He would have been illiterate, uncouth with only his labour of worth to anyone. He survived, he sent money home and I am here. Most people, if they dig a bit will find similar stories in their history. Wherever we are born, whatever the colour of our skin, we are all people with the same basic needs.
Our immigration and asylum system has been under funded so people who could be working and contributing to our economy can't because they are still waiting for documents and those who would be sent home are being held in hotels and hostels. It's easy to focus on the wrong issues, particularly if there are articles published which encourage us to do that. Other countries are processing many more people than we do and doing it efficiently, why aren't we?
