No, work is how things are accomplished. The most fundamental economic activity of human civilization is agriculture. It literally puts food on your table. You could argue that some economic activity is superfluous or downright harmful. Usury, speculation, drug dealing, pornography, all of which are Haram. Yet work is the basis of human society itself. I've scraped a living working in illegal conditions doing the work society needs, like building roads and homes. Am an actual working class man, and I've read Marx as well. Communism is evil, it leads to systemic genocide and enslavement of Muslims and Christians. My Ummah in China picks slave cotton for the corporate profits of American fashion brands and Beijing is undeniably zionist occupied.
Starting a business and seeking self-employment in order to adapt to economic conditions and employment discrimination has caused me to reflect on this as well, employment and labor, profit and power dynamics. Between sociopathic WEF billionare and church bombing USSR communist I think there is room to be a good and honest man. The small family farms that dot the hills of Appalachia are legally considered to be small businesses and many of their owners succeed by their own honest toil. In contrast, my ancestors were illiterate sharecroppers who were continuously exploited by dishonest merchants and landlords.
To say that work is a fraud is a lie, and to say that hard work makes one rich is also a lie. Otherwise, the child workers in the mines of the Congo would be billionaires. Luxury? I despise it. Nabi Muhammad, salallahu alayhi wa salam, lived in a small home without any signs of luxury. It was in his power to live like a rich man, but he refused it in order to do right by the poor. He was himself an illiterate orphan by upbringing.
The question remains: What can be done about the oppression of the rich? I believe the answer is in Islam. The Koran and Sunnah, the Shariah, provides the blueprint of a society where everyone is sheltered and fed, where the rich are under a mandatory and proportional tax ordained by God to give to the poor, and where the oppressed are commanded by God to fight their oppressor and destroy tyranny.
