Indeed. But unlike here in the UK, worse poverty on the material side of things is much more widespread. The intelligentsia (which has specific meaning in a Russian context) has not always been rich, and in most cases in Soviet times had living standards the same or not too dissimilar to skilled workers. Their sense of being a cut above is less to do with the accumilation of lots of stuff, but more based on education (formal and high*) and cultural tastes, although the two are connected. The very rich are vulgar. Mind you, they are anywhere.
*Which is partly why I once had a silly cow in Moscow transposing her own prejudices and treating me less than courteously when she discovered I don't live in London and have never been to a university.
