I don't know that the OP is taking the problem seriously when the majority of homeless people are refugees, unemployed people whose homes have been confiscated,... and in the case that the OP mentioned, I think there are not many.

Going back to the main issue about the lavish spending of children born into rich families, I see the problem as a balance: if they can afford to pay for those things, they have the right to do so. I don't know if you can imagine, people who have money also know how to share it with charity, so don't just judge negatively, but be fair to all sides.
