A town of one street, one church, and one idea - but what idea?

Bucarest has been described as a town of one
street, one church, and one idea. The aphorism is
to some extent justified, for the Calea Victoriei is
practically Bucarest, the Greek Church knows no
dissenters, and the prevailing idea is the spending
of money.

From Maude Parkinson's Twenty Years in Romania. Walter Starkie writing a few years later quotes the same tag but he assumed the one idea was sex. Both meanings sound spot on in contemporary Bucharest but that would mean two ideas. Although some times the two ideas are not wholly unconnected.

Romanians have bought 15 Ferraris worth EUR 200,000 each since the crisis began but this is the most unsurprising news item I read this year
