The core thesis of Das Kaptial is that labourers should share in the profits of their labour & in ownership over the means of production - it's effectively a more pointed version of Smith's scattered critique of landlords and economic rent in Wealth of Nations.
Read a damn book.

Had Adam Smith written Wealth of Nations 90 years later, in Marx's time, it would have probably echoed many of the criticisms of labour exploitation that were described in Das Kapital - the seeds were there in his disdain for those who profit without producing. 
Marx and Smith would have likely disagreed on how best to structure such arrangements - Smith was big on rewarding risk, and Marx was more concerned about the material realities of an exploited class of workers - but those are not irreconcilable philosophies.
jfc It's been well over a decade since I had to write essays on all these damn texts, they all all free from copyright you can go read them *right now* - the naive US-driven takes on them are childish and rob you of valuable critique of the economic systems that you live in.
