Let me see
Conservatives caused the long recession, great depression and Great recession with their policies of deregulation.
Liberal policies caused the greatest innovation, expansion of our middle class and freedom for the little guy in history twice. Once during the 1900's with the anti-trust laws and the break up of the barons and again after FDR's new deal.
Conservative policies are very bad for civilization. Their policies have always benefited the very few at the tops be they kings, dukes or Barons since as long as civilization has been around.
Always fighting to keep the lower 80% down! A fair and just government is needed to demand fairness for the lower parts of our society and that is why liberalism needs bigger government,,,,Government that works.
