Learning a new language is not the only barrier to being a resource producer, I would opine that it may be one of the smaller ones.
This is such a broad, and unsupported statement as to be difficult to accept. Some refugees have skills and drive. Many do not.
I guarantee if you start shipping refugees to floating off-shore platforms, and involuntarily commit them to debt servitude, you will not gain any friends.
Refugees cannot keep their traditions, not primarily because they are forced to integrate where they end up, but because there was some problem with where they came from. If everything was great without changing anything, they wouldn't need to flee the situation. My own ancestors had to give up clan warfare and distrust of strangers to become successful in America, and to the extent that certain families kept those traditions in certain regions of the US, they are among the most backward, poor, and benighted areas of my country today (Scots-Irish hillbillies in Appalachia).
Anyway, one of the greatest strengths of Western Civilization is the ability to integrate, adapt, and adopt. The West gains far more from the influence of immigration than it costs to integrate people.
Giving anyone anything they are not invested in, is a waste of time and resources. Not just a waste: it's counter-productive and often makes things worse. Even giving a family member or personal friend a gift is only worthwhile because you're investing in a relationship. People don't value what they don't earn, and they don't want exactly what you want for them or what you think that they want. So it's not just a matter of having excess resources available, it's also a matter of using them fruitfully, in accordance with individual needs, according to the best judgement of those with the most applicable and complete knowledge of those needs- the individual him/herself.
Are Syrian refugees asking for European assistance in building themselves some Seasteads?
