And this is super short term data. Imagine how much better they are in long term, after assimilating and finding good jobs, founding businesses etc. Poland was losing population and in general not topping development charts, but immigrants fill this gap and boost the economy.
PS: an anecdote - I'm now an adult immigrant in Poland. I'm paying approximately 39.5% of tax now, a crazy rent to the Polish citizen landlord and all local products and services. I won't be eligible for Polish pension for two more decades, and after that I'll probably get some minimal one because I've started too late. I'm also paying some incredible sum to the healthcare system (included in those 39.5%) while not using it much. Statistically the most ill human groups are kids and elderly. Immigrants skip the kids stage themselves and elderly part is very far into future, so they are net gain in the healthcare system.
PS: I don't mean that these restrictions are bad, maybe they are needed. I mean that often it seems that anti immigration ire is directed on the ones can be found the easiest, legal migrants who can be sent home with a flick of the pen, without getting from the comfy chair.
“To put their impact in perspective, in 2018, the average per capita fiscal contribution of first-generation immigrants was $16,207. In contrast, the average drain was $11,361, resulting in a net positive fiscal impact of $4,846 per immigrant in 2012 dollars. Multiplied by the number of immigrants present in 2018 (45.4 million), this amount results in a cumulative net fiscal impact of +$220 billion. Adjusted for inflation, that number is 1.2 percent of U.S. GDP in 2018 ($18.7 trillion in 2012 dollars) and 3.7 percent of all 2018 government spending ($6.031 trillion in 2012 dollars). The former number is roughly in line with the Organisation for Economic Co-operation and Development’s 2006–2018 estimates, which are 1 percent for the United States and between plus or minus 1 percent for most OECD countries”
And
”The Cato Model finds that immigrant individuals who arrive at age 25 and who are high school dropouts have a net fiscal impact of +$216,000 in net present value terms over the next 30 years, which does not include their descendants. Including the fiscal impact of those immigrants’ descendants reduces those immigrants’ net fiscal impact to +$57,000. By comparison, native-born American high school dropouts of the same age have a net fiscal impact of −$32,000 that drops to −$177,000 when their descendants are included (Table 31).”
"The report finds that the total net contribution in 2018 by native Danish people was +41 billion DKK. The contribution of immigrants and their descendants was net negative at -24 billion DKK (Table b)"
The greatest cost is that they also have expectations like shelter and functional services. Germany failing to meet this expectation was not caused by immigration. Immigration is not to blame for Germany failing to modernise its bureaucracy and its infrastructure.
1. Migration is not distributed equally, it will mainly affect metropolitan areas
2. Metropolitan areas are usually doing well economically, but housing can become an issue. Not only due to foreigners, but also because people move in from the countryside and tourists need accomodation
3. Metropolitan areas are also not voting right wing
That means the areas voting against immigration are the ones who experience its impacts the least, except for the fact that young people tend to migrate away from these places. If that comes as a surprise to you you didn't look at the numbers.
The argument against migration in Germany isn't rational or economic, it is emotional¹.
The next question woud be whether these right wing parties are actually gonna reduce migration numbers. They don't have any incentive to do so as people vote them based on that — people who vote based on emotion not based on track record. So it happens that under some right wing governments migration numbers are actually higher than under other governments before and after.
¹: I recall seeing a German family on the subway who in shock proclaimed: "Oh mh god, there are so many foreigners" as she clutched her bag. I, a blonde blue eyed guy, asked her how she knew I was Austrian and that she does not need to worry since I have rode with that subway for 6 years and never seen or heard of any crime being committed, but whether she trusts me as an foreigner is another question — usually they mean: brown people.
I invite you to provide any credible evidence to this statement.
