Well, it's been thirty years now. Thirty years since "Reaganomics" was begun and what has been the result? For many at this site I suspect that this time frame may exceed their memories (they may not be old enough). Some of us though do remember a time before soaring budget deficits, wild military spending and destructive un-restrained greed.
There was a time when one worker could support a family. Typically mom could stay home to raise the children and nurture productive citizens. Now it takes two or even three incomes just to keep a family in a home.
Middle class families could expect to send their children to college, save for retirement, go to the doctor and even have two weeks of paid vacation. Not any more. Now more and more people are slipping into a "new" class of American citizens, that being the "working class", those who work low paying jobs which provide no benifits and leave people living pay check to pay check. AKA the working poor.
Before "supply siders" began setting national policy America was the greatest producer of finished goods in the world.
While that is all true it isn't true that reaganomics or supply siders are the full cause of our declining living standards.
The women's lib movement, globalization, dropping the gold standard, a world wide trend toward service sector economies as well as Wall Street gone to the wolves each had as much to do with our declining fortunes as did reagonomics.
And just for shits and grins the economic state just before Reagan took office was as bad or worse than it is today.
Are you old enough to remember 13.58% annual inflation?
Historical Inflation data from 1914 to the present
How bout 10.8% unemployment?
I might add that Fed policy alone has been more disasterous than Reaganomics.
But FWIW the architect of Reaganomics is on record calling for ALL of the Bush tax cuts to be allowed to expire. Not just hose that effect the top 2%.
