Note that the so-called black book of capitalism the leftists imagine there to be is a reaction to the damning evidence (namely, 100 million dead and millions brutalized/demoralized) presented in the Black Book of Communism.
I've taken the loathsome Leiter to task before on his anticapitalist/leftist intellectual sloth, his one-sided cherry-picking of the evidence, etc. But this just about takes the cake. As against all the data available at ourworldindata.org, Leiter cherry-picks this one article about suicide rates in the USA as evidence of capitalism (i.e., the system of private property, if you can suspend disbelief for long enough to imagine some causal connection) - or the global neoliberal juggernaut, if you will - making life simply unbearable for ever more people.
I mean, why now, all of a sudden, did capitalism get around to upping the despair/suicide rates? Globalization and/or automation outsourced their jobs and so it's capitalism's fault that the mostly-public, mostly-Demo-rat-run education (sic) system was too piss-poor to prepare people for the transition? You basically are in mindless doubling-down territory if you try to keep up a leftist narrative. You'll notice that the 3.5% unemployment rate gets no mention, capitalism gets no credit for that. The number just isn't all that important; by definition . . . let me try to mimic leftist thought processes here for a moment, and tell me if you haven't seen it a thousand times . . . the unemployment rate only includes eligible labor force, those seeking work vs, those who have work, which excludes those who've given up perhaps in hopelessness and despair which is due to the private ownership of the means of production because . . . this is where it gets really tricky and I don't claim to know where it might go from here. One thing's for sure, if they didn't choose to learn from Mises and Rand and the 100 million killed by Reds when they had ample opportunity to do so, then they're probably never going to learn.
Shouldn't these nitwits just stick to the climate-change-discredits-capitalism narrative? It's a lot less difficult to keep a plausible story straight there - that is, until you dialectically/contextually/hierarchically, if you will (considering both presuppositions and implications, etc.) bring in the role of future tech (AI, etc.), in which case it looks like the leftists are losers there, too. Yes, indeed, the age of the neoliberal global juggernaut has brought with it one of the greatest things the world has yet seen - the Internet - and it is true, despite the benefits of all that, despite all the raw data/info it makes available to your average inquirer, it hasn't resulted in particularly improved integrators of data on average across the population.
If anything, given the tendencies of the left-run education (sic) institutions - the case of Leiter being representative of the intellectual rot smugly trying to pass as sophisticated and superior - it has produced inferior information-integrators. What else is the notoriously toxic twitter sewer but a bunch of inferior info-integrators sucking each others dicks (or using mouth on whatever of each others' genitalia) and imagining Trump/America to be racist and everything is getting worse because of capitalism stuff. No, it couldn't be because the education (sic) system is failing to meet expectations, it gets a C-minus or so in the cognitive-skills-value-added dept. despite all the extra dough poured in there, and the taxpayers' patience is wearing thin (advantage: Trump/GOP). No, the thing for the (loathsome) leftist and twitter spittler to do is to double down and blame capitalism (private property), somehow.
But getting back to the real world here: the primary causal factor in human affairs, if you examine it thoroughly and carefully, is the mental and intellectual, with material production value-added a subordinate causal consequence (i.e., historical materialism is conceptually untrue). And something something the fundamental role of philosophy in human intellectual life (and implications for educating children [a proven success wherever tried] as well as everyone else who's eligible in the ways of philosophic inquiry), a point I've been making a lot over the course of this blog (see, e.g., the 'Intro' link, "Better Living Through Philosophy, in broad outline," at the top of this blog posting).
And it'd sure be damn nice if the leftist losers would stop smearing Ayn Rand at every opportunity and actually make an effort to grasp her point (about, e.g., "the role of the mind in man's existence"). The "best" that the academic left has come up with these days is a hit-and-run smear piece by the intellectual thug Scumbag Lisa Duggan, saying that Rand's point is something about being a "mean girl" - that this "mean girl" thing is more centrally and fundamentally connected to Rand's worldview than (say) the role of the mind in human existence or the Benevolent Universe Premise or heroic sense of life. Nope, it's not about any of that; it's about Rand having this chip on her shoulder about those folks who proclaim that man's life is the state's to dispose of; this makes her the mean one here, you see.
The loser-left argues against capitalism pretty much as, well, as dishonestly as it argues against its various lame caricatures of Rand. There pretty much had to be a convergence of both methods and subject matter here (and to a lesser extent this applies to the left's non-response to Mises), since Rand made the fundamental-level identification about the role of the mind/reason/intellect in the capitalistic production process and how that had to lead to the huge advances in the wake of the Industrial Revolution (and the founding of America the nation, as Rand is quick to point out is pivotal to human progress pace the ignorant anti-America leftists smears). As long as the left refuses to engage reality and/or Rand on this point - about the effectiveness of capitalism at bringing out elite intellectual contributions of economic producers (and this may have something to do with yet another interesting cognitive principle Rand identified: unit-economy) - they will continue to fail in their smear campaigns. If they engage Rand/reality on this fundamental point (no thanks to the likes of Scumbag Duggan or Comrade Leiter, who actively destructively interfere with doing so), it will be a win-win.
