Bro we would just keep on arguing. You can keep on thinking capitalism is solely riba and I will keep on thinking capitalism by definition doesnot necessitate riba dealings. An Islamic society can be capitalist as have been many Muslim merchants and communities of past and present. If I look at my home town we have big Muslim entrepreneurs in all major business industries and many of them dont deal in loans at all. So? Is there participitaion in profit making haram? Owning capital like maize mills and big confectionaries and bakeries, cement factories and trading with intent of profit, by means of employing labour, land and other capital which they pursued or acquired through halal means. Many Muslim entrepreneurs started small and now are big names. WE have many examples of them who have tried and been true to ISlamic morals and Quranic teachings. You can blend peoples heads with abstract notions and connect complex and confusing relationships and make your own definitions of capitalism. You are neither being true to academia where you selectively pursue definitions and concepts of capitalism as per your lens and views nor are you true to Islamic tradition by making something haram, many of the capitalistic concepts which are within halal framework aside from the ones ulema have told us are clearly haram ones.
