Wow, while I wasn't looking utopia suddenly arrived. Reminds me of nothing so much as Millerism.
It never occurs to this guy that "the end of the working class" can mean only one thing. The middle class replaces the old working class and becomes the new working class. And that won't be good for your bank account.
We can hope for something better because, for the first time in history, we are free to choose something better. The low productivity of traditional agriculture meant that mass oppression was unavoidable; the social surplus was so meager that the fruits of civilization were available only to a tiny elite, and the specter of Malthusian catastrophe was never far from view. Once the possibilities of a productivity revolution through energy-intensive mass production were glimpsed, the creation of urban proletariats in one country after another was likewise driven by historical necessity. The economic incentives for industrializing were obvious and powerful, but the political incentives were truly decisive. When military might hinged on industrial success, geopolitical competition ensured that mass mobilizations of working classes would ensue.
