Special interests groups NEVER disband. Why?

Some friends and i were discussing groups such as ACLU NAACP women's rights gay rights ect all these movements that are started to achieve goals that are good, and how after the goal is met that they become business, career paths and political springboards that must self perpetuate by "discovering" problems to continue their wars against rather then disbanding and saying "we accomplished our goals" Instead growing into huge money making organizations with political propaganda and lobbying rights that deviate from the original good missions they began as an turning into loud invasive rule makers who try to bend the majority of citizens to sacrifice their basic rights to make room for the special unequal rights of others. This trend also is seen in government organizations formed to achieve a task that eventually become a ongoing expense of a never resolving missions such as the war on drugs. Most people when they achieve a goal move on to the next thing but these organizations become creatures of their own that must eventually be dealt with, Does this make any sense to anyone out there?
