Karl Marx never ran a company, never held political office, never oversaw any accounts, never held a job -- any job. He was supported throughout his life by his friend Friedrich Engles, the son of a wealthy factory owner.
Was he one of you guys, since he wasn't a wageslave?
He wrote for various newspapers, was pretty prominent in academic and philosophical circles, and carried out a series of political and cultural campaigns. He's not a NEET, even though he didn't have a straight 9-5.
Marx. If there's one fucking awful genetic fucking cretin scum piece of human shit I'd wish to fucking wipe from the sneering face of backed-up sewage pipe human history hereafter referred to as "The Black History", it would be that fucking thief, liar, charlatan, murderer, and False Idol erroneously referred to as KARL MARX, also called The Father of What is Now Known as Modern Communism, Sixth Edition. He is THE fucking worst, most abominable bizarre murderous piece of shit who has EVER decided to walk this planet with his miserable filthy fucking lobster feet, that fucking webbed-toe-possessing subhuman ape-man. FUCK HIM AND FUCK EVERYONE WHO HAD DECIDED TO STAND BY HIS FUCKING INFAMY AND CRIMINAL BACKGROUND, YOU FUCKING LUNATICS AND SCUMBAGS
was he a local celebrity at his town's piano lounge?
Critique of society at the time, as well as the laws during and before that. His opinion on religion that you see in quotes and shitty pictures is out of context. He didn't hate organised religion because of their belief in god, but because organised church was supporting capitalism.
His critique of works by other authors like the german ideology and the holy family (sorry I don't know the names of the critiqued works in English) are also pretty good.
All in all, a bit hard to read if you are't familiar with hegel, some decent stuff, rest is bullshit and many people aren't familiar with him.
