Before the Ukrainian conflict a survey of Russians said that a huge percentage of the younger people wanted to immigrate. Even then the people saw little chance of bettering their lot in life if they stayed in Russia. When hostilities started many men of draft age fled the country. Russia (and China) have a huge demographic problem already. The economic drivers are people who are below the age of about forty. They are the ones who buy cars, houses, have kids, etc. Spend, spend spend. Xi was trying to transition the economy into one that depended on its own consumption, but there aren’t enough people to support the economy. In Germany they export 47 percent of their GDP. In the US it’s about three percent. (Depending on how you count it.)
