There may be legitimate reasons to exempt Congress from legislation just like exemptions are allowed for other organizations. The problem is Congress taking advantage of the exemption for the personal benefit of the Congressmen and to the detriment of the citizens of the U.S. Congress has forgotten that the interests of their members and those of the citizens often diverge and seldom are in alignment. I'm inclined to just force complete disclosure first. No more middle-of-the-night, voice votes to hide their devious actions. If complete disclosure doesn't work, then some national plebiscite is in order.
Trusting congress to disclose is folly to me. Legitimate exemptions may occasionally be needed, but less restrictions on society where congress can’t bother being under the same rules is even more attractive.
