I am not so sure really as I have never studied economics, but what I can tell is that money needs to circulate from one's hands to another's, the gap between wages of some people and others need to equalize, there shouldn't be rich fat bankers, or rich fat solicitors, lawyers etc, they should all grind their arse and sweat to the same degree as any other qualified personnel,
so the new world economics should be based on average salaries with no bloody bonuses, this is where all the money has gone out of circulation, it has ended up being stashed away in savings accounts, in foreign banks, instead of circulating widely, among the population of the whole earth as opposed to between the rich of the society.
Nationalise everything, allow people to only own 1 property, and the governments should provide free health care, and pensions, remove other benefits as they are being abused. Lawyers and doctors and bankers etc should all be Government employees, no one gets a big fat bonus or commission, Yup bring back communism if that is what this equates to, at least the gap between the poor and rich will average out and every one will have a fair chance of getting a job, own one house, one car, two children max, and so on.
Isn't China doing fairly well, yes but at the expense of the rest of the world, now that all manufacturing has gone to China, he is getting richer and more powerful, is there any wonder? so why not start opening our own factories and start manufacturing our own goods for our own use, start the engine of economy.
Our Politicians have no clue and they can't do sod all about bankers fat bonuses! the rich getting richer and powerful and the poor getting poor and weaker!
