These points worked when many, really, felt that they were the "little guy." Farm workers, factory workers, even the "company man."
Starting with Reaganomics of the 80s, we steadily moved from manufacturing jobs to service job, so that by the end of the decade, just in time for Bush 1 to lose to Clinton, two-thirds of the economy is based on service. The Wal-Martization of our economy, if you will.
The decade of the 80s, with its high interest rates, made it profitable for Wall Street bankers and investors to facilitate the merger and acquisitions of smaller companies, laying off million of people and dispersing with the assets, fattening the "bottom line."
During the 90s, many young Americans, as well as new comers chose to start their own business. At least they would not be dependent on the whim of an employer. Many had to become "consultants" when they were laid off or were between jobs. And many of these self-employed people see the government as, at best, irrelevant or at worst - a hindrance. Especially when they start hiring help, the regulations that govern employing others, including benefits, are many and complicated.
Many moved across the country for a new job or for a new business someplace else. And as such, you have weak social ties. The only ones, gasp, are the church ties - if you have kids and go to church.
I posted similar thoughts in my thread about immigration
http://www.democraticunderground.com/discuss/duboard.php?az=show_mesg&forum=104&topic_id=2759260&mesg_id=2759260 that previous ones joined unions and worked as factory workers where they could see the importance of caring for your fellow workers and neighbors. But when you are a stock worker at Wal-Mart, or a manager at even Barnes & Noble, when you earn minimum wage, perhaps a bit more, when you are an employee "at will" and you may be saddled with a family to support, student and car loans - it is a lot easier to just think about yourself, your family and immediate circle of friends and neighbors.
