The FT has an article this morning under the headline:
Can you be rich and caring?
The note that there are studies on this issue, saying:
Perhaps the most famous recent series of studies was done by a pair of Berkeley psychologists in 2012. One of these showed that drivers of luxury vehicles were more likely to cut up other motorists and less likely to let other drivers through. The duo also discovered the rich were more likely to cheat, lie, steal and endorse unethical behaviour at work.
And they avoid and evade the most tax too. There would be no tax havens and no tax abuse industry without them.
If you want evidence that they do not care, I suggest the existence of both of them is the clearest that can be given.
