Modeling the US-Europe Paradox

"In 2024 alone, roughly 4.2 million people immigrated to the EU from non-EU countries"

Are those immigrants a net cost to the European economy ?

Would the cumulative effect of paying for those immigrants account for lower European productivity ?

Genuine questions. Happy for "no" to be proved to be the answer.
