Is skills or abilities of the worker taking in consideration in Marx law of value? Is skills or abilities of the worker taking in consideration in Marx law of value?

I know about the subjective theory of value, but I want to know how Marx takes this in consideration

As far as I have been reading the law of value only takes the labour hours work to produce a commodity.


  the more labour it costs to make a product, the more it is worth, and inversely the less labour it costs to make a product, the less it is worth


let's say 


product A 


takes 10 hours
you need specially skills that are a hard to learn
only 14% of population already have those skills to build that product

product B 


takes 10 hours
you do not need special skills
90% of the people already have those skills to build that product



A value = B value ?
I'm not taking about money price

In a real example


A web developer takes 10 hours to make a fancy custom bio web page.
A woodworker takes 10 hours to make a chair.


the chair value = the web site value?

Is the worker him or her self taking in consideration at all?

since worker1 might build a much better web site in 10 hours than worker2
Labour power is a commodity like any other. Its value is consequently a function of the labour embodied in it.

Taking your example,


product A (a webpage)
takes 10 hours
you need special skills (those of a webdesigner) that are hard to learn
only 14% of population already have those skills to build that
product


Versus


product B (a chair)
takes 10 hours
you do not need special skills (you do; those of carpenter. But those are easier to learn, compared to those of a webdesigner)
90% of the people (probably an exageration, but certainly more people have the skills of a carpenter than those of a webdesigner) already have those skills to build that product 


A value = B value ?
the chair value = the web site value?

No.

While each of them requires 10 hours of labour, the labour embodied in each has a different value.

The labour of the webdesigner is more valuable.

Why?

Because it takes - say - 1,000 hours of labour to turn an unskilled labourer into a webdesigner, while it takes - say - 200 hours of labour to turn an unskilled labourer into a carpenter.
