The top 5 'highest quality democracies' as judged by the Bertelsmann Foundation (2018) were all codetermined.

"Giving voice to citizens at their worksites is an important cultural adjunct strengthening communitarian values and expectations of responsive public officials that are central to a high-quality democracy. Indeed, the Bertelsmann Foundation's 2018 global assessment concluded that the five highest-quality democracies were all adopters of codetermination. Its panels of international political scientists judged the quality of American democracy—how well citizen voice or public sentiment is reflected in government policies—to rank only 18th."
