From Foreign Policy
Most Americans tend to believe that they’ve lived under the same form of government, more or less, since the country was founded in late 1700s. They’re mistaken.
It’s true that there have been important continuities. The American conception of what government should and should not do is deeply rooted in clear thinking at the start of the republic; the country has long preferred limited government and effective constraints on capricious executive action. But this persistence of core ideas (and the consistent use of the same buildings in Washington, D.C.) obscures the dramatic changes that have taken place within the governing institutions themselves.
In fact, formidable challenges at the end of the 19th century were met by fashioning a transformation so thorough it could effectively be deemed a “Second Republic.” This new republic came with significantly different economic and political rules — and, as a result, enabled the American system to survive and even thrive for another century. Today, faced with serious economic and political dysfunction, we are in need of another round of deep institutional renewal: a Third Republic.
The conditions that brought about the first transformation of American society are strikingly similar to those we see today. At the root of the problems confronting the United States by 1900 was a wave of innovation that sped up growth. The direct benefits of these new technologies accrued to a few, while many others became more uncertain about their economic future.
