This is known thing in economy science.<p>Most easy to use model of information inequality.<p>What I mean, usually professional know about his specialty magnitudes more than average person from other specialty.<p>On other side, market economy have extremely huge number of products on market. For example, USSR in best its years have about million part numbers nomenclature.<p>How free market economy solve these issues? - They just create infrastructure of entrepreneurs - intermediate actors, who help average person to find product best fit for him.<p>Unfortunately, in Russia entrepreneurs considered as enemy of society. So they have extremely low number of professional entrepreneurs and people just cannot find products in Russia, and shopping near entirely on global market, mostly from China, and Russian engineers just cannot sell their products.<p>Why internal market is important. Well, another model - micro-economy pf business. To make business, one need to make three things: 1st somewhere got knowledge, what to do (marketing); 2nd somewhere got investments (money) and invest them into make ready for market product (finance market, loans, credits, angels, vc funds); 3rd make sells (marketing). Unfortunately, only part of make product (without money) is really strong side of Russians, but they are really weak in marketing and their finance market is on very early stage of development. And as I already mentioned, in Russia entrepreneurs considered as enemy, but also they demonized all business, all things touching credits, investments and finances.<p>And when you trying to go abroad, you definitely will got harder access to finances or investments from other country, then yours. So, usually, exporters enter new country with powerful backup from their own country, and in Russia such backup is just not exist, or to be honest, it exist only for very limited circle of people close to top powers.<p>As said one American professor, Russians trying to get milk without a cow.
