If anything, the main dispute and favor of interest groups is concluded to be pluralism. If all interest groups are able to challenge and influence the official, then everything will eventually balance out. Ever since James Madison argue for expanding the american politics during the early days of democracy, more people were joining factions and being encouraged. The more groups there were in the government, there was a less likely chance that any group could gain a corrupted influence over the government. They also offer more opportunity for participation for politics. By joining an interest group, an individual can push for a policy they care about all the time, not just times of election.
