In speaking of the mobs in Britain (and here), Peggy channels Ayn Rand.
First, she quotes Theodore Dalrymple:
“A population thinks (because it has often been told so by intellectuals and the political class) that it is entitled to a high standard of consumption, irrespective of its personal efforts; and therefore it regards the fact that it does not receive that high standard, by comparison with the rest of society, as a sign of injustice.”
Then she correctly observes:
“Much of what they have is provided by others, but they are not grateful: dependency doesn’t encourage gratitude but resentment.”
