We're having less children, which is creating a problem for the future. If we're not producing more people then it stands to reason that people will look to immigration to fill the needs of society (and fund pensions etc). This is where we then get the people going on about the great white replacement theory.
I want to go back to this for a second.
There is a bitter truth in that Europe as a whole is struggling with a demographic timebomb. There simply isn't enough money being paid into social security systems, and so there's a simple choice: either the local population works longer/harder, or we cut what we pay to people through the social security systems. Some countries are being realistic such as Denmark by increasing the pension age to 70, but others like Poland are stubbornly denying the reality, that either the pension age goes up or the amount paid will go down.
I'm not a massive fan of low paid immigration either (the social democratic view is that low paid immigration contributes to a lowering of living standards), but Europeans as a whole are really struggling to accept that the glory days of high pensions and early-ish retirement are over. I spoke to one retired accountant who moved to Spain when I was on holiday, and he said straight out that the numbers simply don't add up. Interestingly, he blamed the school system for giving people unrealistic expectations.
Parties like Reform will always gain support by shouting about things that people don't like, but the truth is that they always struggle when they come to power as there's simply no way around the reality. Looking at Italy, while Meloni has done quite a lot to reduce illegal immigration, she's also been issuing huge amounts of work permits to non-EU citizens. The end result is that there's still a lot of migration, just that shouting about illegal immigration is an effective way to cover up the fact that you're admitting a large amount of legal migration. The last Polish government did exactly the same thing: they shouted about illegal migration while selling at least 250,000 visas and overseeing a massive boom in migration as a whole to the country.
Of course, part of the problem is that there's a lag between implementing a policy and seeing the effects of it. Millennials like me saw in our childhood how it was common for people to retire to Spain on fat final salary pensions, and I have family friends who are in their 80s and living in Spain on insanely generous pensions. One of them has a pension from British Telecom, which in his position as a local manager is paying out incredibly well, but this was effectively funded by ripping off the taxpayer for years, first as a government agency and then as a private business.
There's no way that I'll get the same thing without some very shrewd and clever investing, and even then, it's likely that I'll have to manage my portfolio in retirement to ensure that it keeps paying out. Is it any surprise that people in their 50s and 60s are now drifting to Reform, because they want "what it used to be like", without realising that "what it was like" was largely based on high taxation and a fairly large amount of exploiting the taxpayer?
