>>413812>Given taht the calculation are to be done in labour hours, how would the SNLT in labour hours for each object be derived?I am 99.9% sure this gets answered in the book if you keep reading.
Basically you do what Marx already alluded to and count all the compound labor and make an aggregate.
If you make a wooden chair, the labor isn't just your assembly. It's also
1. Getting the wood
2. Getting the hammer
3. Getting the nails
You can break this up further:
1. Transporting all these materials
2. Someone tending after the trees
3. Someone mining resources for the purpose of building the hammer and the nails
You can break this up further:
1. Materials needed to create mining tools
2. Materials needed to create transportation means
And so on. You can do this over and over again, although you will get accurate results after a few iterations. The calculation problem doesn't exist and was formulated in a time where computers where actual human beings counting things and not data processing machines, certainly not the supercomputers of today (although Cockshott demonstrates that even moderately powerful 90s computers would be up to the task).
