Celebrities stingy?

I was watching the news this morning about 3 yr old Maddy MCCann. She was abducted last week through her resort flat window while vacationing with her family. I am impressed and amazed at the numerous British celebrities who have donated millions to find this child. Although at the same time I am saddened by that as well. Every minute in this world a child is abducted and yet, do you hear about it? We mostly hear of the high profile cases. Rich families seem to take the spotlight away from the impoverished ones.
My next complaint would is why don't the American celebrities do this as well? Are they that stuck up in "their world" to help raise funds when a child goes missing? Take Trenton Duckett (2) of Leesburg, Fla for instance. His family came up with a mere $20,000 give or take. They had Mark Lunsford, father of Jessie Lunsford who met her fate in the hands of a repeat sex offender, AMW John Walsh, father of murdered Adam Walsh (killer unknown) and Nancy Grace. Yet, no one capable of donating large amounts to bring this baby back to his family came forward? Too busy? The money raised came from Trenton Duckett's father, Josh Duckett's persistant outcry to the public, and local businesses. But the small donations were thwarted by the family of baby Trenton's mother, Melinda Duckett. Melinda committed suicide 2 weeks after her son went missing. If she knew where he was , she took it to her grave. We are Americans. We've always been the ones to open our hearts and our pockets, tight as they may be to come to the aid of others. Are celebrities that live in this nation too good to help aid in child abduction donations?
The celebrities overseas should be commended for thei help with Maddy's reward fund. They include Simon Cowell, JK Rowlings, The Beckum's, and a business man (who I apologize to for forgetting his name, but made the first donation) and I'm sure I'm missing other names as well.
I will continue to pray for the Duckett's. Trenton has found a special place in my heart. Never will I give up hope. My prayers to Maddy's family and all the other children that are stripped from their lives and families lives.
