Charities already enjoy the extreme generosity of tax exemption status. Governments in the last few decades have gotten into the habit of providing social services through subsidizing charities instead of building and maintaining properly funded government programs - it is a band aid approach that can open the door for corruption.

One of the reasons that governments like this approach is the funding is always temporary - like year by year contract stuff - so the workforce is always tenuous - and workers in the charity field are generally not paid the same kind of living wage that a real government employee would qualify to receive. Think of it as a small army of underpaid temp workers that supplement basic government programs on a temporary overflow basis.

Governments get used to having these surplus programs around - and use them as a crutch to patch broken parts of the social safety net instead of actually fixing broken social programs. For governments, it's just easier, and more politically expedient, to give the money to them.

For example - you have social programs that teach literacy, life skills, stuff like how to make a resume - etc - these programs are mainly aimed at compensating for the failure of the public school system to produce functionally literate graduates.

Either you pay enough to get the job done right on the front end, or you pay to clean up the mess on the back end.
