WMP holders should mostly be the common folks. In "Marxist" countries, workers are forced to be big savers, especially in China with its one child policy. The government basically gets deeper into debt to its own population - with a power of monopolist debtor though. The Chinese Party "enterprenuers" benefited very handsomely from cheap borrowing (at negative rates, essentially). Their profits are priveleged to be saved by various means. Options are different for the wide population.
