Neo Corporatist is the best one

In order for interests to actually be expressed to the government, the neo-corporatist system is the best form. The pluralist system does not work efficiently because all of the “voices” become convoluted. There are too many groups with not enough membership to actually have their opinion heard. This can prove troublesome for the government, as the number of interest groups can be overwhelming for the government.  On the other end of the spectrum, the controlled system is very bad for the public. The interest groups are not actually there to represent the voices of the people, so they are not effective interest groups. The best system would be the corporatist system because it has enough membership in the group to make their voice heard, and the system does not become too fragmented. Thus, the neo-corporatist system is the best form structure for interest groups.
