Again, I don’t think inequality can be measured in wages alone since urbanites had much more access to in kind services–housing, transportation, leisure,
health care etc than collective farmers. Another statistic I have from Verbitskaya is that in 1950, 72-92% of kolkhozy in several central provinces paid less than one kilo of grain per work day. 4-8% kolkhozy in those regions paid nothing at all. Things improved by the mid-1950s, after procurement prices were raised. But sill a kolkhoznik earned only half the wage of a sovkhoz farmer and 36% an industrial worker.
France has basically some pockets of insanely expensive real estate. You can usually tell them by the nearby presence of horrifying tenements built by the local government to provide subsidized housing with their corollary of urban squallor, such as long closed shops. If you drove the A8 highway behind Nice and Cannes you know what I am talking about: insanely priced real estate near the coast and some of the most depressing tenements this side of ex-Soviet Central Asia behind.
I won’t even go near Paris because it may be the heart and brain of France but it’s effectively a parallel universe.
It’s called “crisis” for a reason
Stalin did not only privilege the Soviet elite with higher wages. He also provided them with far superior housing (think of the great Stalin era apartment buildings, which provide elite housing even today, with the so called “House of Lions” built to provide housing for Soviet Marshals and Generals being perhaps the most ostentatious example). Stalin also provided the elite with superior access to food, clothing and consumer goods as well as (horror of horrors!) domestic servants (think of Margarita’s maid in The Master and Margarita). The Stalin era was also the time when the various “Gosdacha” settlements were created in and around Moscow for writers, scientists, military officers, political leaders etc. Stalin himself had the use of several Gosdachas including the famous one in Kuntsevo. When on leave in the Crimea his favourite residence was the Vorontsov Palace. In a book I recently read about Stalinist architecture I found that even restaurants during this period, though often of very high quality in terms of food and service (in contrast to the situation in the later Soviet period), were strictly off limits to anyone except those specifically granted access to them.
