For Quartz, I looked at the US's role as a global offshore haven writ large - and how much worse things will get under Trump:
But this isn’t simply a federal problem. A handful of states have also helped the US become an international leader in providing shell companies. Delaware, Nevada, and Wyoming currently lead a raft of states offering guarantees of privacy in return for expanding their anonymous clientele—a service accessed by leading arms dealers and foreign kleptocrats alike.
Indeed, in the largest shell company survey to date, conducted by trio of academics, US shell company providers were judged to be the least transparent of any jurisdiction surveyed. Said one analyst with Global Financial Integrity, “In some places [in the U.S.], it’s easier to incorporate a company than it is to get a library card.” Or as one of the authors of the shell company survey later wrote, there “is strong reason to think that the United States … is the worst in the world when it comes to regulating shell companies.”
