impacts of mass migration.
We'll not avoid it, whatever our views on that and politics.
The Belarus crisis will pass, however much of the world is truly ****** and people will do anything to get from there to places they perceive as better. A few decades ago, there were major advances in medicine. Those advances cut infant mortality massively. There was not however a major advance in living standards or education, nor were there pensions of universal health care introduced, nor was there a reduction in crime or in conflict. For a lot of the world, having as many sons as you can push out is the difference between starvation later in life and survival.
I worked in Africa for 3 years until just before the covid. In one of the poorest countries on the planet. The median age there is 19, and that country's meagre resources have not responded and that country's former colonial overlord (France) is happy for its companies to sell them cheap tat and tinned food but still does its best to stop them making anything to sell or developing their economy. This is repeated worldwide.
Plus, the world is getting hotter and some places that were already hard to scratch a living in are getting harder. Nigeria already has over 200 million people and will reach 300 million before the century is out. Yet the Sahara (which already covers part of Nigeria) is visibly growing year on year.
In Iraq, whole extended families live on 500USD to cover food for a dozen people, education (not free), housing and medicine. (and many families don't even get 500) while the country's oil revenue disappears somewhere.
20 years ago, people in the developing world were crowded round black and white TVs if they had access to one at all. Now, there are cheap Chinese smartphones and they watch TV and films on them. Sitting in squalor but watching all the bling of American TV series which seems like unimaginable wealth. And they want some of that. Who wouldn't?
It isn't about Poland (most people in the world know nothing at all about the country) except that the Poland Belarus border is a weak spot. There will always be weak spots and right now, the biggest is here.
