It's easy to be charitable...

...when it's not your money (Greg Mankiw). Shouldn't those who suggest governments should do more to help cause xyz (UN Dispatch) be the first to lead by example?

Unlike Mankiw, who presumes forethought and planning, I can't say I'm surprised. Using the heavy hand of taxes and government is coercive at best and corrupt at worst (Accuracy in Media) working best when you have the freedom to spend on behalf of others - especially when you think you're better than everyone else (Pajamahadin / Never Yet Melted).
