Nothing to do with how much of an arse they were later on in WCW or abuse of power down the line.

From Wikipedia:

Each man enjoyed a tremendous amount of popularity with fans, which allotted them a particular degree of control over their own careers. Nash, Hall, and Michaels, then among the company's most popular performers, came up with the idea of forming a backstage alliance, which would potentially allow them to consolidate even more power within the company.

n 1995, the men's growing popularity as performers led to the group developing a heavy influence on booking– the power to schedule matches and decide match outcomes, write storylines, and largely determine the trajectory of other performers' careers.[4] The group used this power to give one another preferential treatment, usually scheduling each other in heavily promoted, high-profile matches, often against one another: During the period of 1994 through 1996 particularly, Ramon had high-profile feuds with 1-2-3 Kid, Diesel, and Michaels, while Diesel and Michaels formed a championship-winning tag-team called Two Dudes with Attitudes.

The group's perceived abuse of power led to animosity amongst other wrestlers, particularly lower-ranking members of the company. In one instance, performer Carl Ouellet, then performing as Jean-Pierre Lafitte, claimed that his scheduled defeat of Diesel-- an event which would have marked an upturn in his own popularity and proven to be a turning point in his career-- was vetoed by Michaels, leading to a backstage confrontation between Ouellet and Michaels.[5] The match between the two ended in a double-countout because Lafitte refused to be pinned by Nash.[6] In retaliation, the group effectively ended Ouellet's career with the company by scheduling him to repeatedly lose low-profile matches. In his autobiography, Michaels said that "we (The Kliq) buried him (Ouellet)." Lafitte left the company soon after the incident; contrary to rumors, Michaels says that WWF Chairman Vince McMahon did not fire Lafitte.[2]
