I don’t think there would be popular support for those two changes, which would seriously damage our human rights.
Until recent years, anyone wanting to live in another country had to apply for permission. I never heard anyone question that, and I went through the same process each time I moved to another country. They have the right to choose who they want!
It’s understandable that people living in poverty-stricken, badly governed, war-torn or crime-ridden countries would prefer to live somewhere more comfortable. But Europe and the Anglosphere do not have room for everyone who wants a better life.
And those arriving on small boats are predominantly young and middle-aged men — their home country’s workforce, and the least oppressed sector of any population.
If the boats were full of women fleeing Afghanistan, Iran or Saudi Arabia, I would have a lot more sympathy, and would be fund-raising to support them.
But the present influx of demanding men, often with mediaeval views and without in-demand skills (and refusing to live in France, which is one of the world’s most civilised countries), is a burden many people reasonably think we should not have to bear.
