In my limited experience huge swathes of the so-called alt right are, regardless of their other political positions, just as dismal about their economic future as the young left, and they have no illusions about concentration of capital, etc, since the 80s and have drawn similar conclusions.
I understand a little of what you're saying in your second paragraph, and personally I prefer the term 'working poor' instead of 'working class'. Since people these days can work 3 jobs and still be poor. But these kinds of definitions are not what should be focused on. I think you're missing the forest for the trees.
I see no evidence for the argument you make in your third paragraph. Nor do I understand why you read this as some neo-fascist trick on class consciousness.
Class is a term that relates to an individual's relationship with the means of production in a society. The means of production is the capital property, of course, the businesses, the factories, productive agricultural land. This relationship is material, meaningful, and provides a precise description of class in society.
Class is not about whether you swing a hammer or use a Macbook.
Hacker News comments are not the appropriate place to learn or teach any of this, because quite frankly I'm tired.
The Communist Manifesto is twenty pages. It's available freely online. Yes, it's greatly simplified propaganda from the 19th century. That said, you should take an hour to read it, and then hit up Wikipedia, look for counter arguments, whatever, make up your own mind - once you do, see if you come back and believe that Krein knows much of anything at all.
To be frank, I think your sort of self-satisfied academic left rhetoric is a large part of the problem, and so you are so in love with it that you've fundamentally misunderstood the writer's argument, which is a great deal closer to your position than you seem to realize.
