Should public officials be banned from trading individual stocks?

The county commissioner in rural Ohio is a deliberately misscaled example. A local official with a small 401k and no ability to move markets or shape federal legislation isn't where this structural conflict lives. The conflict lives in Congress — in senators sitting on banking committees, representatives voting on drug pricing legislation, executive officials regulating the industries where they hold positions. That's where the power to create the misalignment exists, and that's where the ban needs to apply. Using the most sympathetic, least powerful example available to argue against a policy targeting the most powerful officials isn't a rebuttal. It's misdirection. You also conceded the structural conflict exists — your own words: "Lucifer makes a solid point about structural conflicts, I won't deny that." At that point, the debate becomes purely about what resolves it adequately. Your answer, across three rounds, has been stronger enforcement of existing laws and better disclosure requirements. But the STOCK Act has existed since 2012. Violations are documented continuously. Fines remain negligible. That framework has had over a decade to prove itself and hasn't. Restating it in the final round as the real fix doesn't make it one. The "opaque funds" objection is an implementation problem, not a principle argument. The solution isn't "therefore let officials keep trading individual stocks." It's "ban individual stocks and require blind trusts or broad index funds" — instruments that are transparent, regulated, and don't create the sector-specific conflicts that individual positions produce. That's the structural fix. Transparency requirements leave the conflict intact and visible. Elimination removes the condition that makes the conflict possible in the first place. One of those is a solution. The other is a monitor on a problem we've decided to keep.

The claim that a six percent annual outperformance proves information asymmetry relies on outdated research, since the widely cited figure traces back to a small sample 2004 study of 1990s Senate trades, while larger and more recent analyses covering the post STOCK Act period from 2012 to 2020 show congressional returns much closer to the broader market and sometimes underperforming simple index funds once fees and timing are factored in, and even where excess returns do appear correlation is not proof of inside knowledge given that officials tend to be wealthier and more financially literate than average investors and wealthy individuals as a group already outperform retail traders regardless of political office; the signaling problem argument also undercuts itself, because if the public cannot distinguish skill from information advantage under current disclosure, banning individual stocks does not remove that asymmetry but simply pushes it into real estate, private equity, or a spouse's holdings where there is no disclosure at all, trading a visible and auditable signal for an invisible one, and the claim that a ban resets the incentive structure ignores that reelection, party standing, and post office career prospects already dominate legislative incentives far more than any stock portfolio; if the real concern is material non-public information, the proportionate fix is tighter restriction on access to that information and stronger real time disclosure rather than banning an entire legal asset class, and the fact that virtually every credible ban proposal still permits diversified index and mutual funds despite those being just as tied to overall policy outcomes reveals that the underlying issue is optics rather than a genuine incentive problem.
