Be fair. The far left is just as insane. They are currently in much smaller numbers than the far right but it hasn't always been that way. I distinctly remember when the opposite was the case. The GOP was a center right party and the Democrats were a far left party. It took several devastating losses in the 80's before the Democrats shifted towards being a center left party in the 1990's under Clinton and the DLC.
I wish there were a far left, I think that died with the sixties, had a brief rebirth during the occupy movements and a few protests against global economics, but people are too comfortable today too concerned with money and status.
Two authors detail the death of concern for everyone, Galbraith and Judt.
"Something is profoundly wrong with the way we live today. For thirty years we have made a virtue out of the pursuit of material self-interest: indeed, this very pursuit now constitutes whatever remains of our sense of collective purpose. We know what things cost but have no idea what they are worth. We no longer ask of a judicial ruling or a legislative act: is it good? Is it fair? Is it just? Is it right? Will it help bring about a better society or a better world? Those used to be the political questions, even if they invited no easy answers. We must learn once again to pose them." Tony Judt 'Ill Fares the Land'
"The United States in the 1980s devoted 5.2-6.5 percent of its gross national product to military uses; Germany devoted less than half that, Japan less than 1 percent...The American resources so used were at cost to civilian investment and consumption; those so saved in Japan and Germany were available for civilian use and specifically for improving civilian industry. The matter of the use of trained manpower was particularly important. By some calculations, from a quarter to a third of all American scientific engineering talent in recent years was employed in relatively sterile weapons research and development. This talent the Japanese and the Germans devoted to the improvement of their civilian production. Japan, defeated in war by American industrial power, has now in peacetime extensively replaced its erstwhile enemy in productive service to the American consumer." John Kenneth Galbraith 'The Culture of Contentment'
"'Practical' politics, it is held, calls for policies that appeal to the fortunate. The poor do not vote; the alert politician bids for the comfortable and the rich. This would be politically foolish for the Democratic Party; those whose primary concern is to protect their income, their capital and their business interest will always vote for the party that most strongly affirms its service to their pecuniary well-being. This is and has always been the republicans. The Democrats have no future as a low grade substitute.." John Kenneth Galbraith 'The Good Society'
"Capitalism is the ownership and use of the concrete but dynamic elements in a society - what is commonly known as the means of production. A capitalist is someone who produces more capital through the production of the means he owns. This necessitates the periodic reinvestment of part of the capital earned into the repair, modernization and expansion of the means. Capitalism is therefore the ownership of an abstraction called capital, rendered concrete by its ownership of the means of production, which through actual production creates new capital.... However, capitalism as conceived today tends to revolve around something called the profit motive, even though profit is neither a cause of capitalism nor at the heart of the capitalist action. Profit is a useful result of the process, nothing more. As for the ownership of the means of production, this has been superseded by their management. And yet, to manage is to administer, which is a bureaucratic function. Alternately, there is a growing reliance upon the use of capital itself to produce new capital. But that is speculation, not production. Much of the development of the means of production is now rejected as unprofitable and, frankly, beneath the dignity of the modern manager, who would rather leave such labour and factory-intensive "dirty" work to Third World societies. Finally , the contemporary idea of capitalism grandly presents "service" as its new sophisticated manifestation. But the selling of one's own skills is not a capitalist art. And most of the jobs being created by the service industries are with the exception of the high-technology sector descendants of the pre-eighteenth-century commerce in trade and services." p360 'Voltaire's Bastards: The Dictatorship of Reason in the West' John Ralston Saul
