The Left has done an excellent job over the years of portraying Republicans as the “party of business.”
There is an unfavorable implication to this title in a society in which many – unknowingly viewing life through a Marxian prism – aided by propaganda in academia and the arts, have a negative view of private enterprise as consisting of miserly Scrooges and evil Montgomery Burns’s accumulating vast wealth on the backs of the poor.
To be for business in their zero-sum worldview is to be for those who have achieved wealth and status, the devils to the poor, meek and downtrodden angels, angels stuck in their position thanks to evil businessmen and an inherently unfair society.
The Left personifies (Soros and facts aside) or at least purportedly supports the underdog, and how can you oppose the underdog?
As with most all disinformation campaigns, this portrayal was based on a kernel, and perhaps even more than a kernel of truth. Republicans historically promoted economic policies such as tariffs that “protected” certain favored businesses, at the expense of consumers who thereby were forced to pay higher prices for goods.
From a cultural perspective, Leftist radicals were against “the man,” from Madison Avenue mad men to the dutiful suburban Ward Cleaver types who upheld the traditional order, and who were decidedly not Leftist radicals.
In more recent times, such lines have blurred to a degree, as politicians have conferred benefits upon shifting industries and constituencies, and in turn received funding and votes from varying blocs as the political winds have shifted (see the financial services industry in 2008 and 2012). Remember, despite there being “fat cat” Republicans like Mitt Romney, the chief venture capitalist in all the land, and overseer of many many Solyndras, is Barack Obama.
