Why has it failed? The simple answer is that Americans like what progressivism has brought them. Here's part of a thought-provoking article by Fareed Zakaria (pictured) in The Washington Post on why conservatism has failed:
For decades, conservatism was a dominant ideology in the Western world, championed by Margaret Thatcher and Ronald Reagan. Now, it has quietly collapsed. President Trump’s populism has taken over the Republican Party, and Brexit fever has consumed Britain’s Conservative leaders.
Into this muddle comes George F. Will’s “The Conservative Sensibility.”. . .
The book, as one might expect, is deeply erudite, filled with examples from history and illuminating quotations from politicians and poets. Will has attempted to outline the basic features of his creed. American conservatism, Will announces, has almost nothing to do with European conservatism, “which is descended from, and often is still tainted by, throne-and-altar, blood-and-soil nostalgia, irrationality, and tribalism.” He paraphrases Thatcher in observing that “European nations were made by history, the United States was made by philosophy.” American conservatism, then, is a project that seeks to defend the original philosophy of the Founding Fathers: classical liberalism, which promotes limited government and the veneration of individual liberty.
The counterpoint to this tradition, Will argues, is progressivism, the philosophy articulated by Woodrow Wilson and most capably enacted by Franklin D. Roosevelt. Born during the industrialization of the country after the Civil War, progressivism sees society as requiring collective action undertaken by government, which can best enable individuals to flourish economically, politically and morally. This tradition, for Will, has eroded the ideals of the American founding, enervated the spirit of America and created a country that is less free, less self-reliant and poised for economic stagnation.
But the problem for Will and for modern conservatism is that, as progressivism rose in the 20th century, the United States became the most powerful, productive and dynamic nation in the world. Indeed, after the New Deal came the astonishing American boom of the 1950s and 1960s. After the Great Society came the information revolution, which the United States has dominated more than any other nation. The fact remains that in 2019, the United States is one of the most free, dynamic and innovative countries on the planet. If that is the result of a century of progressive policies, maybe we need more?
The fundamental flaw of modern conservatism is that it is unsure whether America today is a fallen republic or an astonishing success story. This confusion has produced a political crisis among conservatives, which might help explain the rise of Trump.
Ever since the 1930s, conservatives have been promising their flock the rollback of the progressive agenda. They have warned about the dangers of leaving the welfare state intact and pilloried conservative leaders for failing in this crucial task. Yet, despite the Reagan revolution, the Newt Gingrich revolution and the tea party revolution, the welfare state is still standing as strong as ever. Republicans dominate almost every arena of U.S. politics — and the state is bigger than ever. Should we chalk this up to incompetence? More likely, conservatives know that the public actually wants the welfare state and that a modern country could not function today under some libertarian fantasy experiment. Of course, they will never admit this.
In any case, the result is that conservative leaders left their base permanently aggrieved, feeling betrayed and distrustful of any new campaign promises. In recent years, as the fever grew, conservative voters became desperate for someone who had not played this game of bait-and-switch with them. And into this rage walked Trump, who easily toppled the old conservative establishment and rode the frustration with elites all the way to the White House.
The moral of this story is PROGRESSIVISM WORKS!
