Why is "Deinstitutionalisation (orphanages and children's institutions)" trending?

Wikipedia Overview

Deinstitutionalisation is the process of reforming child care systems and closing down orphanages and children's institutions, finding new placements for children currently resident and setting up replacement services to support vulnerable families in non-institutional ways. It became common place in many developed countries in the post war period. It has been taking place in Eastern Europe since the fall of communism and is now encouraged by the EU for new entrants. It is also starting to take hold in Africa and Asia although often at individual institutions rather than statewide. New systems generally cost less than those they replace as many more children are kept within their own family. Although these goals have been made internationally, they are actively being working towards as reform and new reforms are put into practice slowly as is fit for each country.
