countries shouldn't take in more refugees than they can accommodate -Pope Francis

On a flight back to Rome from Sweden, pope Francis was asked about Europe's migrant 

crisis and he said that even though countries shouldn't  'close their hearts' to those in need, they should be careful not to overstretch themselves. He told reporters:

'Governments must be open to receive them, but also do the calculations regarding their reception (capabilities), because one must not only receive a refugee but also integrate them. 'Because so many are arriving That there is no time to make provision for them and that they can find schools, homes, employment, and learn the language. Prudence has to make this calculation.' 

He also said that it poses a dangerous situation if the migrants are not integrated into their host communities.
He added:

'What is the danger when a refugee or migrant is not integrated? He is ghettoized, that is, he enters a ghetto. And a culture that does not develop in relation with another culture, that is dangerous.'
