Of course that phrase is understood in the UK. All I was saying, if you would ONLY read it correctly, as no-one should feel guilty of they either had enough money themselves not to need to work (unless they wanted to) nor should they feel guilty if their families were wealthy enough and WILLING to maintain them That`s totally different from sponging off people who CAN`T afford it, or even trying to "lay a guilt trip" on someone who, though able to afford it isn`t willing to do so. So much depends on the attitude, and situation of the recipient.
Of course even in that enviable position, many people want to employ themselves doing something, even if not for financial gain. I can`t understand why the thought of anyone being in that position should upset you so much? Is it just envy? I certainly don`t envy anyone who can live in that way. I might wish I was able to do so myself, but I don`t feel angry or envious because I can`t! I`m quite happy being me - I don`t want to be anyone else, however rich or privileged they might be.
