We ought to allow only ex-elected officials to lobby within their competence. That way we can be sure ethical conduct will be understood. It's also a way to keep our wisdom close to Congress after office. Corporate parachutes to make up for lost wealth is a means to endless lobbying anyway - for a few companies needs that are championed in phone calls instead of represented on Capitol Hill. When lobbying morphs into a clear mechanism for promoting issues over perspectives it will facilitate the trend of ex-politicians hanging around Washington longer, more often.
