Codetermination could jiu-jitsu the problem of corporate political speech (e.g. Citizens United) into a feature, rather than bug, by making corporate interests democratically representative.
"Shareholders are not really owners, and they exercise little control over corporate political involvement. Employees, communities, consumers, and other stakeholders exercise even less. The reason why corporate political speech is so corrosive to democracy is that the benefits and prerogatives of the corporate form are marshaled to bolster the speech of a tiny sliver of the financial and managerial elite. The fact that corporations speak is not itself a problem; whom they speak for is."
