My tone is reflective of my mistrust of your intention, I am sorry if that is uncomfortable.
I wanted to remind people as to make political analysis not too easy by taking the mental shortcut of reducing current capitalism on the problems pointed out by Marx rendition of LTV.
On the contrary, I think applying theoretical models to current real-world economics is the only way to make sense of where theory and reality deviate. I don’t consider it a mental shortcut at all. The only prerequisite for it being a useful exercise is to be explicit about where those deviations occur when they arrise. When theories are publicly dismissed wholesale without elaboration it can cause confusion about what the intent is, and there are plenty of those who *do * aim to drive wedges between those in the working class.
I would have found it more interesting if you had been more specific in how you think LTV was being misused.
