listing foodbanks, homeless , economic inequality issues are not unique to the UK, you could be describing many so called first world countries even the US where these things exist as well. As for the curtsey thing I would think it makes no odds to the queen whether people do or do not unlike the very old days when a period in the Tower of London or maybe lose your head if you didnt show respect to the Monarch. As shown in the photo actually performing a curtsey is not an easy thing to do elegantly anyway versus a simple bowing of the head.
