Do fundraisers donate to charity?

I’m not sure if this is the type of post that will get people riled up or not.  But I’ve been wondering (from a marketer’s point of view):

Do fundraisers donate more money and/or more frequently to charity than others? 
Why am I wondering about this?  What do I mean when I say, “from a
marketer’s point of view?”
Well it seems to me that…  if fundraisers donated more money to charity more frequently, then they would have a better understanding of what it feels like to be a donor.  And their organization’s marketing/fundraising tactics would improve, become more successful, and be more donor-centric.
As a whole, the industry would raise more money.
Nonprofits would achieve their missions faster.
Thank you letters would go out more promptly.
There would be more transparency.
Donors would see the results of their investments more often.  They’d understand precisely how their donations are making an impact.
Poorly composed emails would be revamped.
Spamming would stop.
Donors would no longer be frustrated.
Nonprofits would no longer waste so much money on actions that make donors frustrated.
Silos would break down.
And more.
So, does anyone know if fundraisers donate more money more frequently to charity?
