How do you think retired people are classified by Marxists? The class distinction does not mean "work until you die" , it means "you need to/have needed to work to live". So no, you're not a "demi-capitalist". You're still a worker. Because you had to work for that capital. You didn't inherit it/exploit it from the surplus value you extracted from laborers
What good is this sort of binary differentiation? Someone like Zuckerberg would technically be working class because he worked for his money, despite his negative effects on the world.
It's a starting point to my understanding, not an end all be all categorization. It helps get across that the only useful distinction worth making is between those who work, and those whose capital does the work for them
I don't know Zuckerberg's biography but I'd wager to say he didn't have to work or starve ever in his life. And I'm no Bhaskar Sunkara but I'd also wager to say >50% of zuckerbergs wealth is due to the surplus labor value his employees create, not his labor. So in a material examination of Zuckerberg you'd say indeed the issue is not the phase of his life where he worked for a living, but the phase where he is extracts maximum surplus labor value from his workers. That phase constitutes X-99.9% of his wealth, so he is not exactly some hard to pin down edge case
This isn't to say that any company that derives a profit is an evil exploitation factory, it's just an idiots understanding of a useful jumping off point for material analysis.
