President Obama is dividing America into two nations—one rich, the other increasingly poor. Yet, surprisingly, both "nations" are more likely to elect Democrats. Those Americans who are growing richer support the president’s economic policies, and those growing poorer become dependent on him for government largess. Together, both groups elect Democrats.
While driving declining living standards for most, the economy has not performed well in this century.
Obama “recovery” has only managed  2.4 percent growth and George W. Bush’s expansion accomplished about the same rate of growth and then collapsed.
Since 2001, when Bush took office, the U.S. economy has created only 4.7 million jobs—about 30,000 a month and less than one-fourth of those needed to keep pace with population growth.
Technology is important. The digital revolution and the shift of news and entertainment to the Internet, cable, eBooks, and the like have effectively killed one million jobs.
Globalization is a culprit. American industry still boasts many of the best products and efficient factories but has shed 5 million jobs—far more than can be justified by rising productivity.
Manufacturing has enjoyed a small renaissance but has recouped only one in nine lost jobs, because Bush and Obama poorly enforced trade agreements that apply to principal competitors. China, Japan and Germany systematically maintain currency advantages and barriers that artificially under price their products and block our exports.
