Classic remarks in Marx's "Das Kapital"

Capital comes to the world, from head to toe, with blood and filth dripping from every pore.

Capital is afraid of no profit or too little profit, just like nature is afraid of a vacuum. Once there are appropriate profits, capital becomes bolder. If there is 10% profit, it is guaranteed to be used everywhere; if there is 20% profit, it will become active; if there is 50% profit, it will take desperate risks; for 100% profit, it will trample all human laws; if there is 300% profit, it will be used everywhere. For profit, it dares to commit any crime and even risk hanging. It encourages unrest and strife if it brings profits. Smuggling and the slave trade are proof of this.
