these all are very different in the UK. Rich people widely painted as evil. It is immoral to have more than average Joe in this country. Newspapers have cliche 'filthy rich' (often being used in conjunction with pulications about city boys).
I drive E class merc and after I left it in public parking places a few times - I twice found fat spit full of mucus on my door and once it was thoroughly scratced with a coin.
This is my very incencitive to move to day trading. I really dream about moving as far from London as it will be technically possible (ping time to my broker).
=============================================
maxima --- to ask me, who responds to most things with my tongue firmly planted in my cheek, to be serious for a moment is difficult, but given how "people" from EVERYWHERE tend to be jealous and/or envious of those with MORE than they have, what you say is of no surprise --- purchase an older austin 7 that is rusting and allows you to appear to be as poor as a churchmouse and leave the merc at home, as this may solve ONE problem at the least, and for the other, make as much as you wish, move to your own estate outside of london, and thumb your nose at those who do not wish to "extend" themselves and better their circumstances.
while we certainly have much the same in the US, its "possibly" a bit less (except in the very heart of urban areas, like NYC itself (which i guess is pretty much the same as London)) if only because were a bit less of a "class" society than you Brits (or at least thats a bit more of your history)
I grew up many years ago in one of the richest towns in one of the richest counties in the US --- these were people who had money essentially "forever", lived in the "family estate" and clipped coupons for expenses. They drove OLD fords and chevys, dressed "down" to the point you might actually think the "lord of the manor" was actually the janitor or groundsman and had NO "airs !"
they were NOT hated then and I wouldnt know if they would be hated now, but if one is near the poverty of the inner cities, the jealousy and envy creates many a scratch on a mercedes, and just imagine what an aston martin would engender !
GO -- get rich --- live nicely and forget about the refuse of life !
