I always look forward to reading Peggy Noonan's "Declarations" column in the Saturday WSJ. This morning's was one of the most interesting because her analysis of the cause of the London riots got to the root of everything that is wrong and destructive about Liberal ideology. She quoted Theodore Dalrymple of the City Journal who described the problem perfectly.
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.
And Ms. Noonan closes the comment with this perfect summation.
Much of what they have is provided by others, but they are not grateful: dependency doesn't encourage gratitude but resentment.
If we don't get things straightened out soon and Liberalism relegated to the scrapheap of failures, we have our population of entitled dependents trashing our cities and randomly attacking people.
