Russia is definitely not richer than Latvia. GDP per capita in Latvia is almost double Russia's, even using fraudulent Rosstat data that predates the recent crash in the RBL: https://en.wikipedia.org/wiki/List_of_countries_by_GDP_(nominal)_per_capita

The minimum wage in Russia is 16240 RBLs/month = about $160. In Latvia it’s 620 euros/month ($675).
