I think nurses do a great job, however.....
Putting people on guilt trips, no matter how much they earn or what job they do, isn't going to get them to donate their money.
They pay their taxes like the rest of us, and personally, would hate to see 40% of my salary going to the fucking taxman.
Most would agree that nurses/teacher should be better paid, and if the government sorted their shit out maybe, it will change, but I doubt it.
There are a decent percentage of our players who donate a hell of a lot of their own money to charities, good causes, so trying to pick the right one is an impossible task and one that will never meet with general approval.
