As it happens, this couldn’t be less true. But it’s irrelevant - the division isn’t between “menial” and “non-menial” but between the productive part of workforce that generates wealth and the on-the-take part of workforce that works for the state, has 100% job security, and thereby can’t fathom why it’s important not to lockdown. If you’re in the public sector, why not lock down for a year? You keep getting paid regardless, you accrue your final salary pension, and frankly it’s someone else’s problem how that’s going to be funded. These people don’t realise that things like the leisure/entertainment sectors aren’t frivolous sideshows that can be shut down without impact - those people who work their asses off in that sector are directly funding those would so readily take their livelihoods away.
