There is no malice in this, although it's very easy to perceive it as so. It's purely a side product of democracy - our representatives cannot possibly (or feasibly be expected to) represent the professional or personal interests of each and every working person within their constituency without those interests being put forward ahead of time and chased - hence why the questions go out to those that are 'known to know' for advice. It's human nature - if you know someone who has experience in a domain you're unaware of, you go to them for advice. If the representative doesn't know you have this expertise, they're not going to come to you for advice.
We all take for granted that our representatives in government look out for us, however when these initiatives are raised by them, and input is requested, the questions asked are very rarely put to laymen or individuals or groups with a cursory or passing interest. They're usually put to those working in the related industry or those who have a stake in the arena, as this is where the expertise is perceived to live, and will generate the quickest consensus on the issue.
It's all down to exposure - if you are invested in an issue, find a way to get involved (reach out to you representative etc.) and have a voice in the discussions, rather than waiting idly by and demonstrating against the result.
