I’m not from the US and will probably never understand US politics, but wouldn’t Democrats be on the side of working class and the most needing parts of the population? The democratic party has been ruling for the past 3 years and from 2008 to 2016 (basically just a 3 year interruption in the last 15 years) so why are we facing now a situation of social inequality and those who work for a living (as opposed to non-productive classes) are struggling the most?
