Face it: Marx was partly right about capitalism

Readers of Anthony Trollope will remember how thoughtless and greedy young men in the Victorian professions can be lured into ruin by accepting ‘accommodation bills’ from their shifty acquaintances. They make themselves liable for the debts of others; and only too late do they discover that they are trapped in a web of financial mechanics that forces them to pay hugely inflated sums for obligations or services they have had nothing to do with. Their own individual credit-worthiness, their own circumstances, even their own personal choices are all irrelevant: the debt has acquired a life of its own, quite independent of any real transaction they are involved in.

A prescient student of Trollope would have seen that he is identifying an endemic feature of the world of borrowing and lending. A lender takes a calculated risk in offering the use of their money to someone else, and rates of interests express the recognition of this — and the rewards that may be secured for taking such a risk.
