“Capital hates the absence of profit or small profits as nature hates vacuum. If the gain is adequate, it becomes brave: if 10% of gain are secured, it is ready to invest in any place , 20% and it heats up;  50% and it becomes reckless; 100% and it tramples on all human laws; 300% and there is no crime that it dare not commit, even at the risk of the gallows. When it can make profit through disorder and discord, it encourages both, as evidenced by the smuggling and the slave trade”.
 
Karl Marx in “Capital”
