Russia's middle class, according to the Russian business journal Kommersant, has remained stable for the past 15 years at approximately 20% of the population. Citing government statistics, the journal predicts that the current economic crisis will reduce the percentage of Russia's middle class to 15%.
Do we really need that the in front of Russian business journal Kommersant? Is it only true of inanimate objects that we stick a definite article in front of their descriptive phrases because most of the time, as far as I have noticed, we don't usually put one in front of titles that follow people's names (if we do, that's called false titles or something like that, for example—the Greek mathematician Euclid)? Clear things up for me please.
