Maybe the poor will not be afraid and have no time to be afraid. Just to survive has exhausted all its strength. The rich are afraid of losing wealth, while the poor may lose life.
What is the chance that a billionaire may lose all of his wealth? Such people may be having assets spread out in dozens of countries, and the investment portfolio will be diversified. The worst possible scenario may be a 80% or 90% reduction in wealth, but it can't get any worse than that. But for the middle class that is not the case. Their portfolio is not diversified. Remember what happened during the disintegration of the USSR? A lot of people suddenly lost all of their savings, because hyperinflation destroyed their pension funds.
