But I think this kind of moral approach is precisely why right wing parties have been winning globally, in the US and elsewhere. For many voters, the overwhelmingly important thing is individual economic security and personal/familial safety. Full stop.
And so if you force them to choose between a morally off putting party that at least claims to care about their problems, and one that is ostensibly morally less bankrupt, but hand waves away those problems – they’re going to hold their nose and vote for the former. Shame and outrage doesn’t work in a society that is uncertain and scared about its future.
It seems like a handful of candidates are beginning to understand this, in the US at least, but for some reason this level of realpolitik is just beyond many center and center-left parties.
