> and defer overly to expert opinion

The term 'expert' here actually means well-funded lobbyists who pay to have access to the politicians. They are able to present decision-makers with convincing arguments to pass laws that are favorable to the ones funding the lobbyists. They are smart and they are experts, but they are also laser focused on using that expertise to get what the funders want. This is almost always an outcome that is bad for regular people.
