While it seems to be a red rag to a bull for large swathes of the electorate in many countries, this is one of the things having a reasonable system of inheritance tax could presumably help reduce. The extent to which people can creatively hide/structure wealth to pass on to their children, creating a "landed gentry" class of sorts, seems to get worse with time. I certainly have observed anecdotally a large gap between those who inherited and were able to invest in property, and those who didn't and could not.
It was interesting to observe the Conservative party in the UK revisit this issue (again) at their party conference, it's amazing how much it riles large sections of the UK electorate when only less than 5 percent of families in the UK ever actually meet the threshold where it has to be paid...
