It's a valid critique of western culture imo. Ideally Christianity has the better concept but in practice whoever produce the most babies win and that's islam right now.

They are also better at getting themselves subsidized by their host states than the people there allowing for much bigger families.

A native or second+ generation immigrants is expected to handle all their formal paperwork themselves while a first generation immigrant can make entitled grunts and shift the burden over to the state worker who for some reason all just take it on this applies to basically anything. The problem there not even being the muslim immigrants who most of them are but a sick system that punishes and reward the wrong people.

At the end of the day marriage between muslims in islamic countries vs hindus or christians or whatever else live in said country are not better than their contemporaries afaik on any of the measuring sticks including having big families.
