Let me give you a concrete scenario. Say a congresswoman from Iowa wants to buy stock in a small seed company because her farming constituents tell her it’s promising. She has no committee assignment related to agriculture—she’s on the transportation committee. Under a ban, she can’t buy it. That’s her personal savings, her retirement money, tied up because of a rule that assumes she’s corrupt.
I get your concern about conflicts, I really do. But a ban treats everyone like a potential criminal before they’ve done anything wrong. We don’t do that with doctors or judges—we have ethics rules and enforcement. The same should apply here. Tighten the recusal rules, make blind trusts mandatory for sensitive positions, and actually prosecute insider trading cases. That solves the problem without stripping away a basic financial right from every official in the country.
