As to the royals role in charities, and yes that is good.

But, is it not much different and much the same role as some other rich folk and celebrities take? I suspect if they were not there, the role would be filled by others in the spotlight.

Some celebrities do it for genuine concern (for example Willie Nelson, Bono, and the Ex Mrs Paul McCarthy), and I suspect some do it it increase their popularity. Save the wildlife, feed the kids, ban land mines, help the farmer, respect history, all good causes with celebrity and rich folk support to increase visibility...good stuff.

But, don't expect the royals to "speak out" on highly controversial topics, those that are in dire need of public attention.
