Can you interpret these sentences.
There is also a case for encouraging spaces in which people from different backgrounds meet and interact in order to increase the chances of cross-class friendships. Given the increase in geographical inequality, with rich people increasingly living in neighborhoods of rich people, only hospital wards and places of religious worship are sites of genuine social mixing.
Would you give me a general concept of these sentences? Specially in these cases "There is also a case for encouraging spaces in which..."
And the part with "hospital wards and places or religious worships are sites of genuine social mixing."
