The answer to this question is tribes

The correct answer to this open question is the following.
Yes, the growing number of interest groups support US Senator Byrd’s conclusion.
There is too much money involved in interest groups, and an increasing number of these groups have been appearing in the United States political scene. Senator Byrd was worried about this increased number and lack of control over these groups. Let's have in mind that these interest groups hire lobbyists to negotiate with legislators and offer support. But the US Congressmen had to be aware that it is the citizens that voted for them and put them in Congress as their representatives. So they serve the people, not the particular agendas of interest groups.
