I agree in spirit, but this is overbroad. The various branches of government employ millions of people. A cop, or VHA nurse, or my friend who works a non-managerial role at the EPA can own stock. It's the decision-makers who were should be concerned about. That group extends beyond congress, but doesn't contain literally every government employee.

I don't think normal middle class government workers owning stocks is a real problem. I get where you're coming from (technically they could have inside information), but it's not nearly as impaction as the elected officials having very large swings hinge on their own policies.
