ditch what cannot be used.
Yup.
What's more important: capital or the "ditched" labor?
I suggest that you will never be appointed spokesman for the capitalists. Labor has a lot more guns.
And there we have it, in a nutshell.
But, the funny thing is, it doesn't matter how many capitalists you shoot, you can't coerce them into being good capitalists. That's why the Communists just lined them up and executed them.
Capitalism is purely volitional. Capitalists will not act as entrepreneurs unless there is the possibility of extraordinary gain, worth taking risks for.
And labor has no clue about how to be an entrepreneur. That's why labor will always be labor.
