The point of the article quoted is that a portion of the population is spooked by the possibility of conscription and have left their jobs to go into hiding. That number is beyond the number of people conscripted.@Z.W. Wolf Russia has almost 150 million population, and they mobilized 300 000, which is 0.2% of the population, or 1 in 500 people. Granted that includes children and pensioners, but if an economy collapses when less than 1% of the workers become unavailable, there's something else wrong with that economy.
I'd be interested to hear whether the claimed knock-on effect of smart people leaving the country can be quantified.
