The days are over when technology can be advanced in laboratories by individual scientists alone. Now you need an army of lawyers to negotiate the hazardous terrain of interlocking patents. Unless we find a solution to the problem of interlocking patents, the patent system may actually impede the very innovation it was designed to encourage.

Gore Vidal, the American writer, once described the American economic system as 'free enterprise for the poor and socialism for the rich'. Macroeconomic policy on the global scale is a bit like that. It is Keynesianism for the rich countries and monetarism for the poor.

Rich countries have 'kicked away the ladder' by forcing free-market, free-trade policies on poor countries. Already established countries do not want more competitors emerging through the nationalistic policies they themselves successfully used in the past.

Between the Great Depression and the 1970s, private business was viewed with suspicion even in most capitalist economies.

Corruption exists because there is too much, not too little, market.

If we are really serious about preventing another crisis like the 2008 meltdown we should simply ban complex financial instruments, unless they can be unambiguously shown to benefit society in the long run. This is what we do all the time with other products-drugs, cars, electrical products and many others.

Making rich people richer doesn't make the rest of us richer.
