It has been shown repeatedly in multiple studies (you might have heard a very prominent one from Denmark) that Non-European/Non-Western migrants are a net loss for the economy during their lifetime and also their children are a drag on the economy. Meaning the money spent by the government to support them is never made back (from the working) during their whole lifetime.
So no, most migrant groups are not a big benefit. Especially considering that this is only taking the economy into account. When you take into account the societal disruption and anti-values that they bring with them, then its clear how negative they have been for Europe.
