What barriers are there to communication in social isolation?

there are many but some can be physical, psycological and natural, you do the math!!!! Edit: Religion and culture set the social barriers between communication. Resulting from those you have language, economic, racial and ethical barriers.

Edit: The most prominent barrier of communication in social care would be who gets access to social care and who does not. Social care is not distributed everywhere, even in the places of highest concentrated poverty. Health & Social Care is actually a system that belongs to the government. Thus, the government decides what individuals and groups to extend social care to. Or whoever runs social care facilities decides where to implement social care. Other barriers that would apply to this would be economical and racial barriers. It would seem that most of social care is provided to groups of minorities and old-aged citizens. But middle-class has equal access (if not more) to social care. However ,there are many variables that can prevent someone from having health & social care benefits such as being an illegal immigrant, not have insurance or medicare, etc.
