On the other hand, right-wing government itself lowers limit of pandemic threat: they will be able to ignore a much more dangerous epidemic than a left-wing one will be forced to act upon, crippling the economy. Just simply because right-wingers have larger capacity for absorbing human losses. Plus, it puts thermostat effect massively into action as epidemics are much more dangerous to older and less educated people so they shift society to the left.
