"Once the champions of people who came home from work with hands dirty from toil and sweat, too many establishment Democrats went over to the dark side, taking up the cause of the well-manicured executives (think: Goldman Sachs) who write the checks and the mercenaries who deliver them (for a substantial cut, of course). 

The lust for loot which now defines the Democratic establishment became pronounced in the Bill Clinton years, when the Clinton-friendly Democratic Leadership Council (DLC) abandoned its liberal roots and embraced “market-based solutions” that led to deregulation, tax breaks, and subsidies for the 1 percent. Seeking to fill coffers emptied by the loss of support from a declining labor movement, Democrats rushed into the arms of big business and crony capitalists."
