Actually Marx said capitalism was a positive historic development.
> So X - Y, is what? Pure profit in bosses pocket? Not really...It's the cost of everything needed for the company and for the worker to do their job
When I said...
>> What happens with that $1000 in sales? $800 of it goes to buying wood, nails, hammers etc.
...that is what I was covering.
> cartels, oligopolies, monopolies are so damaging
Marx goes into cartels, oligopolies, and monopolies a little bit, but they didn't really hit their stride until after he died. Lenin is who covers this in Imperialism, the Highest Stage of Capitalism. They both go into great detail of why it is economically and politically impossible to stop cartels, oligopolies, and monopolies from forming. Lenin mentions Standard Oil in his paper, which the government tried to break up in 1911. As Lenin knew then, it is impossible to stop monopolies, which is why the old broken up parts of Standard Oil reformed in the 1999 ExxonMobil merger to become the most profitable company in the world, as well as the company with the third largest revenue in the world. And I can go on and on about how government can't break up monopolies (the Bell breakup only lasted a few years, now AT&T and Verizon control most of the US wired last mile and wireless).
