It was not a complaint. It was an observation. Very few people are independently wealthy and can afford to work for free. The organization has expenses that have to be met. If they do not meet those expenses the organization will cease to exist. That is why keeping the money rolling in is the number one priority and has to be. It is that way for churches, the Red Cross, the Cancer Society and every other group.Does this really MATTER? Does it change the discussion in some way?
Kind of like saying "The airlines don't care so much about TRAVEL as they care about making money, so they'll only travel if people pay them."
The people who do this work day-in and day-out do so because it is their passion. But they can't do it without money, both as operating capital for the organization and in the form of salaries so they can feed their families while they do their good work.
These "they just care about the money" gripes are petulant and self-defeating.
If an organization loses badly when it tries to go after even laudable goals, it will be seen by those who are funding it as ineffective and the funds will stop coming in.
As for the NRA, most members have long forgotten or never knew that the NRA was part and parcel of helping to set the terms of both the NFA and the GCA. They looked at both and decided it would have little effect on either hunting or target shooting and said "no problem". In any case, the NRA just did not get involved in politics to any significant extent back then.
The NRA's involvement in politics grew over time and really blossomed after the member revolt in Cincinnati in 1977 when it became clear to a lot of members that if the NRA did not become politically involved, there would be no hunting or target shooting down the road. IIRC, the ILA had only been formed a few years before the member revolt, and was not yet particularly effective because there was no clear goals set out for it.
The old guard still mostly cared about hunting and target shooting and just did not see any danger to either from the new laws that were being passed with regularity across the country and nationally.
Some understood what was really going on and realized that these laws needed to be fought.
