The masks will continue to be more contentious in the U.S. than the vaccines. Masks are, at their core, an altruistic public health measure (we wear them to protect others) meant to help preserve societal institutions (e.g. not overwhelming hospitals). After 40 years of neoliberal/Libertarian/Objectivist propaganda convincing at least a third of the population that altruism is for suckers, that government will always fail, and that there’s no such thing as society, the reaction to masks in the U.S. isn’t surprising.*
So any chance of enforcing this public health measure is left up to self-interested for-profit corporations, which (as with content moderation) are wont to cut so many corners as to make enforcement of such a mandate either impossible or dangerous to employees.
[* and that’s before you get to the Q-nuts who believe that the masks signify knowing or unknowing membership in a (((Satanic))) paedophile cult]
