Well to do folks can work from home, or not work from vacation homes, have all their needs delivered, and not catch this thing. All the "essential" people will catch it and some will die, and the well off will consider this very cheap, good, proper, and mandatory for economic reasons.
It's hardly worse than the exploitation for profit of the tobacco industry. Known for decades it would maim and kill, but millions invested in, were shareholders, were owners. And they've never been sanctioned. This will be no different. The lower class will take one for the team, again, for the greater good of society so that the better classes can live with minimal inconvenience.
By all rights, essential workers should quit. But they have a boot on their head: landlords and debts. It's economic coercion.
