Although I am not very familiar with Russian society. But many men in China marry women in Russia. And post videos on social media to introduce the lives of the two countries. Overall, Russia gives me a feeling. Except for Moscow and St. Petersburg. The healthcare system in the vast majority of regions is poorly constructed. The social welfare system is also not sufficient. China has a well-established public healthcare and education system. Compared to other countries, the expenditure on healthcare and education is not high. People just hope their children receive better education and frequently hire private tutors. Even in all rural areas. If you are willing to pay a fee of $20 per year. You can also reimburse 80% of the medication, hospitalization, and surgical expenses.China's exchange rate is managed, so it's not that relevant. Govt income and job growth are more important. The problem with China is education is expensive and there's no universal healthcare. So people can't afford having families or falling sick, even if they have jobs.
Russia's military expenditure is not a lot for wartime, just 30% of govt expenditure. If they stop growing it beyond 10-12T rubles, then normal growth will reduce it to below 25% by 2030. And they don't have much govt debt, just 16%. They also have social security, free education and universal healthcare. So they are working with a different set of rules compared to China.
