As an economist i have to strongly disagree, I've been telling people that the sytem is due a colossal crash for years now, but because i dont have 30 years experience, a beard and am not right wing enough (these are the "elitist" version of economists), I have been generally ignored (as most other sane economists in my age group 25 - 35). When it did crash the puppets in government just went and propped it all up again (i'll give it another 6/8 years before it all falls down again.
Luckily the capitalist/liberal economists are dying out (literally) and the new guard acknowledges that different systems are needed in different countries according to their development level and that social welfare (not Socialism - there is a difference) is a must for any developed or developing countries. Developing countries need strong state control esp in regards to their trade and industrial policies whilst developed countries need to make sure the potential for equality is allowed (not enforced) across the whole population (i.e. the same provision of services at the same quality level for all citizens regardless of wealth - free universities, schools, cheap transport and free healthcare for a start).
Rant over.
