There is a handful of rich people out there who'll dip into their pockets...but the problem with that is that we only see those who do give to charity, and so then assume a lot more do than don't as a result, because we don't realise how many rich cnuts there are out there who aren't well-known celebrities and who keep themselves out of the spotlight.
Remember reading a decent article about how big a thing this is in the US. The likes of Bill Gates create a culture where we see billionaires as fairly benevolent liberal types who give back to society. But the reality is that there are a lot in the background who keep a low profile and spend their time actively lobbying for unnecessary tax breaks to further enrich themselves at the expense of the wider population. We just never hear about them because they keep away from the media.
