The definition that @Paradox25 is excellent. Unfortunately, it isn’t what most people mean when they talk about liberalism today or in recent American history.And I don’t think it is what Blackberry meant in the question. Currently, it means a movement favoring policies such as Franklin D., Roosevelt advanced, as opposed to the laissez-faire capitalism and free-market rule of the Gilded age. The reason such policies seem better for society than what passes for conservatism today is that they are far better for the society in general.
From 1933 when FDR took office till 1980 when we entered Reagan “conservative” Revolution, America enjoyed a growth in GDP that outstripped even the Gilded Age of 1865 to 1895. We created the world’s first vibrant middle class. Unlike the Gilded Age that benefited only the rich, the slough up out of the Depression and the subsequent Post War Boom lifted us all, poor and rich alike. We gained the 40 hour work week, paid vacations, holidays, sick leave, health insurance, a living wage and a social safety net for those that fell on hard times or suffered a medical disability.
In short, we became the world’s most prosperous nation. And in doing so, we did not pile up massive debt as conservatives would tell you. Quite the opposite. Our debt hit 120% of GDP at the end of WWII and over then next 30 years we had paid it down to 30% of GDP, Then Reagan launched the Conservative revolution. Reagan tripled the national debt in just 8 years.
Like the distortion of the word “liberalism”, what we call conservationism today is far afield from the dictionary definition of that word. Today’s conservatism is aimed not at preserving existing social structures (what the word means) but rather at tearing them all down and dragging us back over a century to the policies of the Gilded Age or even further back to those of pre-war Southern states. It is radically regressive as opposed to liberal/progressive politics.
The Gilded age did produce a burst of growth before exploding in the Great Depression. But that growth benefited the Robber Barons and the giant trusts, not the average American. There was virtually no middle class. Most Americans were held in wage slavery. Hired thugs were used by the titans of industry to beat and lynch anyone who tried to organize workers. Safety in the workplace was ignored. Child labor was the norm and children worked some of the most dangerous jobs, toiling 12 to 14 hours a day for a subsistence wage. Food posioning was commonplace and ignored by officials who were on the take. That is the America today’s GOP base has been duped into yearning for.
The current conservative movement is funded and informed by a handful of billionaires such as the Koch Brothers and the Waltons, and by CEOs of the world’s largest multinational corporations. For 40 years, they have poured hundreds of millions of dollars into a 50-state network of neo-fascist right-wing think tanks they have set up. Their purpose is to take us back to the Gilded Age, because if they can do that, they will be the Robber Barons and they can add billions or perhaps trillions more to the billions they already control. The GOP today is a cleverly designed propaganda mill mean to achieve that goal for its Greedy Oligarch Pig overlords.
I know that sounds incredibly partisan and harsh. So did it when the GOP called all who opposed them traitors, communists, fascists, socialists, cowards, defeatocrats, surrender monkeys, elitists, etc. etc. The president is a Christian Cult follower of the Rev. Jeremiah Wright and is also secretly Muslim and not even from America. He’s not only secretly Muslim/Christian Cultist—he’s declared war on all religion. Fascism has always used demonization of its opponents as one of its chief tools. Fascism was a corporatist movement, and so is today’s GOP. The policies the GOP advocates will be good for a tiny handful of people at the very top who are already fabulously well off. It will be terrible for all the rest of us.
