Well, tbh, that's why most people who want to provide a service set up their own not for profit or charity, and do it that way.
It's a fine line between an immediate improvement in local services for that specific disability, and further depleting available funds on a more global scale though. Not a prefect solution by any means, but a temporary salve.
I'm not defending any particular organization - but I don't suppose any national disability organization is a joy to work for in a paid capacity now, however altruistic your motives on application were. Politics just means everything is being dumped on the voluntary sector, who are, in most cases, valiantly attempting to buffer the cuts and continue services.
I have a great deal of sympathy for the parents of children with disabilities who make the decision to effectively set up a local organization in opposition (whilst theoretically working alongside) but the issues are the same. You have to raise funding somehow. There are only so many people willing to put in a full work week unstintingly on a voluntary basis.
The state sector dumping on the voluntary is nothing new. But it kinda grates when the users focus on the crapness of the voluntary sector, not the reasons they are so crap in the first place (hello state sector).
Of course, the other issue, is that these well meaning folk who set up to provide a service have a great understanding of the specific disability, but often focus on that to the detriment of the admin or behind the scenes work necessary to ensure they are able to continue. Which sucks. Because they are brilliant at what they do, but can't do it because of the admin burden, or fundraising burden, or because they just can't afford the time in a literal sense.
And then we end up with sn top trumps because we are trying to find support for one child in the face of many equally deserving and needy children. (Needy in the sense they need support, rather than any detrimental comment).
Sucks to be me, etc.
