I don't think violence actually works to solve the problem, however.
In addition to being barbaric, it also has the tiny problem of being ineffective. You can't execute an ideology, you have to out-meme it.
The concept of an above-the-law class has a long and beloved history because us social human beings seem to really love (and require!) having a very clear and well-defined social hierarchy within which one can orient oneself. Most of us would even prefer clarity about the hierarchy and where one resides within it to elevated position within a murkier hierarchy.
You can't get rid of a monarch just by stripping them of their power and installing a parliament; the poor will keep polishing their crowns and spoons for free until the cows come home. You literally have to construct a better meme to replace the fundamental concept. You'll have to out-James Bond James Bond (and Batman and Superman and Jack Bauer and Jason Bourne and friends).
I used to think that the US constitution was an explicitly fraudulent meme promoted by the ruling class (I think Washington was the largest landowner in the colonies?) to usurp, and maybe it was, but this Lincoln quote made me think a little more deeply about it:
> As a nation, we began by declaring that 'all men are created equal.' We now practically read it 'all men are created equal, except negroes.' When the Know-Nothings get control, it will read 'all men are created equal, except negroes, and foreigners, and Catholics.' When it comes to this I should prefer emigrating to some country where they make no pretense of loving liberty – to Russia, for instance, where despotism can be taken pure, and without the base alloy of hypocrisy.
Even Lincoln pointed out we were full of shit. I suppose he's right that it's better to fake it 'till you make it than to not give a shit at all.
