Offering simple solutions to complex problems, especially if those “total solutions” can not be verified because their goal is unreachable has its point as an explanation. Scapegoating too, since it gives the illusion of freedom from responsibility (it’s cheaper to blame immigrants/LGBT rather than assume one’s own responsibilities e.g. for climate disaster). But to me there’s more: in Italy we passed from a radical left populism (M5S) to radical right populism (Lega/FdI) with the pandemic in between. Shouldn’t people realize that simple solutions do not work?
