You're right, it's probably just that. My mistake to read too deeply into someone like this.

I was using Marx's definition, and I am a member of that class, so defined.

My existing wealth and ongoing income of seven figures is derived almost entirely from capital accumulation.

I am knowingly and actively betraying my immediate class interest, here and elsewhere, because I'd rather my wealth increase more modestly to ensure we all live in vibrant society.

I do think it is foolish for salaried white collar workers not to see what is coming and begin unionization efforts; Their interests are ever more misaligned with capital with every year that passes.

How does missing the point and going on an unrelated rant help ensure we live in a vibrant society? Because I’m missing that part.
