Members of parliament are responsible for deciding on the public issues discussed in parliament, yet in the debate preceding such decisions, external inputs are very frequent and very desirable, a.o. to avoid flawed regulation. Currently such inputs often happen via lobbyists, often without a visible trace for the constituency.
For this reason the debate among the interests groups in society tends to be more lop-sided.
Besides the contextual complexity that surrounds any debate in a parliament or committee, the fact that agenda items are not published (or findable) as individual chunks adds to confusion and access-hurdles for people who are only dealing with a specific topic, including the one percent in which they might be experts. Overall one could say that much expertise is not harvested, and many voices are not represented in the parliamentary debate. This results in missed opportunities for society, day after day.
Moreover popular media and the way they deal with commentaries on agenda items do not contribute to a very thorough debate.
