The world economy is made up of many tiny parts that are useful only when we combine them into more complex wholes. The higher the value of these aggregations, the more economic growth. Humanity’s achievements – from the 120 ingredients of my clock to the countless financial deals and developments that produced the internet and flight navigation systems – all result from joining people and things to each other.

That’s why western capitalism has triumphed for the past 150 years: it gave us the best knowledge to explore economic combinations. Capitalism does not need to be re-thought or re-invented; it simply has to be re-discovered.

The reason credit and capital have contracted for the past five years in the US and Europe is that the knowledge required to identify and join parts profitably has been unwittingly destroyed. The connections between mortgage loans and liquid securities, between non-performing financial derivatives and the organisations that hold them; the non-standardised, scattered records that obscure who holds risks; and the off-balance-sheet accounting that obscures many companies’ health: these all make it harder to trust and hence combine. Until this knowledge system is repaired, neither US nor European capitalism will recover.
