Capital can be something wonderful.
Capital is - with reasonable use - practically self-increasing; it is, so to speak, the Gold-Ass from the fairy tale. For those who have accumulated enough of it, it could be redemption, at least the redemption of unpleasant work and economic worries. Adam, as the visionary Hildegard von Bingen wrote 800 years ago, lived in paradise from his property. He "shone" and had great knowledge of all things and beings. He had this knowledge - which sounds amazing at first - because he didn't work! A visionary from the Middle Ages may not be an argument in today's discussion, but if we pause briefly and examine why we work at all, then it seems logical: It's not ultimately the goal of all economic activity, research and work to make life easier and to overcome the necessity of work? To live with knowledge of (and respect for) all beings and things in inner peace out of our property? The term working class does not appear in Hildegard's show of paradise. The term property does, and it clearly expresses a mutual love relationship.
Today's paradise of capitalism, however, has at least one serious flaw. Few are getting richer and richer, while most are currently getting poorer, even if they haven't all noticed it yet. Today's concentration of wealth on a few is probably hardly inferior to the concentration of power on a few during the feudal period. Of great knowledge and respect for things and beings, and a mutual love relationship between owner and property, not much can be noticed after a certain concentration. Seen globally, the inequality is even greater than in Germany, so that capitalism becomes a life-threatening, even fatal catastrophe for many people in its effects. But a paradise in which not all inhabitants are "Paradisees" is an inner contradiction. It's not for anyone, there's no doubt about it.
Capital accumulates most easily with those who already have it, that's what interest does. Interest is also hardly avoidable and sensible, because it is the price and therefore the control for the capital use. What capital does almost without interest, one can observe - as an example - at present at the real estate prices. Interest is not fundamentally reprehensible in other respects either. Ideally, interest is what my property, indeed my capital, gives me back 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, those who accumulate capital to make something bigger and live off it in old age are rather a blessing for the economy. The right problems that capitalism poses for us, for society, arise when the accumulation of the same capital stock continues over generations. That is, if the descendants of a family clan with the inherited fortune, which they themselves did not gain, receive a huge advance over their fellow men. The right problem arises precisely when the market does not work because the conditions for starting and participating in the market are brutally different for people.
