Someone has to justify their job so they set about looking at he usually accepted 3 groupings of folk, recognise all the edges have moved/blurred over time, and invented a load of new categories as a replacement. One that few of the public will adopt long term anyway. 3 groups are easy to envisage, many are not. Meanwhile a slow news period gets the media to make a nose about it to fill space/time so now we're all aware. But generally speaking fewer care these days than was the case say, 50 years ago. And probably fewer then than 50 years previous to that. It is becoming a 'for entertainment only' thing. Sure there is still an elite whose ancestors grabbed most of societies wealth for themselves and their family, or maybe have managed to more recently. And there are those for whom finding the finance to last the week is a constant stress. But generally I don't think we consider such differences very much these days. And even fewer of us put it down to one group being better than another as a class distinction tends to imply. We are all a product of our genes and experiences anyway and whilst the wealthy can pay for a better standard of life they can't yet change their genetic code even if they could judge better from worse.
