She has so much wealth. So much readily available to make a real difference in the lives of real people. For the cost of just one of those trips she could help make life changing things happen for a family who's sole supporter has lost their job, or a family who has medical needs but no insurance. I'd even rather see the money go to no-kill animal shelters to help with the pets people had to give up because they could no longer afford them due to the economy.
Yes, a trip to Australia would be fun but I feel like she is almost "buying" the approval of her fans. Now that I've had time to think it over I'm not impressed with her at all.
