Capital can be something wonderful.
When used sensibly, capital is practically self-increasing; it's like the gold-ass from the fairy tale. For those who have accumulated enough of it, it could be the salvation, at least from unpleasant work and economic worries. Adam, as the seer Hildegard von Bingen wrote 800 years ago, lived in paradise on his property. He "shone" and had great knowledge of all things and beings. And he only had this knowledge – which sounds amazing at first – because he wasn't working at all! A seer from the Middle Ages may not be an argument in today's discussion, but if we pause for a moment to examine why we are working, then it seems logical: Isn't it ultimately the goal of all economic activity, research and work to make life easier and to eventually overcome the need to work? To subsequently subsist on our property in inner peace with the knowledge of (and respect for) all beings and things? In any case, the term "working class" does not appear in Hildegard's exhibition of paradise. But the term property does, and her writings clearly express a mutual love relationship.
However, today's paradise of capitalism has at least one serious flaw. Few are getting richer, while most in the developed countries are getting poorer, even if they haven't all realized this. The current concentration of wealth on the few is barely inferior to the concentration of power in feudal times. At a certain level of concentration, there is not much to be seen of great knowledge and respect for things and beings, and a mutual love relationship between owner and property. From a global perspective, inequality is even greater than in Germany, resulting in capitalism becoming a life-threatening, even fatal catastrophe for many people. A paradise in which not all residents are "Paradisians" is yet an inner contradiction. It is not one to anyone, there is no doubt about it.
Capital accumulates most easily at those who already have it, that is what interest does. It is also hardly avoidable and makes sense because it is the price and thus the control for the capital employed. What capital does, and almost without interest, can currently be observed – as an example – in real estate prices. The interest rate is not fundamentally reprehensible either. Ideally, interest is what my property, including my capital, gives back to me for my attention and care. The owner who has acquired capital through useful work and skilful management is usually not the problem either. On the contrary: Anyone who accumulates capital in order to do something bigger with it and to live on it in old age is more of a blessing for the economy. The real problems that capitalism poses to society arise when the accumulation of the same capital stock continues over generations. That is, when the descendants of a family clan with inherited fortune that they have not earned themselves are given a huge lead over their fellow beings. Precisely, the real problem arises when the market doesn't work because the starting and participation conditions in the market are brutally different for people.
