It is pro-common person, the lower & middle classes. It is a fighter & an advocate for the continual rights of the middle class & grants helping programs to the lower classes in order for them to have a decent life. It is also for the rights of the oppressed & was responsible for many lower income persons advancing into the middle class through free social, health, & educational programs.
It is also responsible for the vast welfare state which degenerated families & created generational welfare. It made some people expect entitlements instead of working smart to make their way in society. It has subsequently metamorphosized into a radicalized, even leftist party within the past eight years- advocating a more equal distribution of income whether one deserves it or not, raising of the minimum wage, & the amnesty programs of low skilled immigrants which is taxing the American socioeconomic system further.
Not to digress further, it is responsible for granting full rights to the LGBT community. It believes in the rights of those who are considered outsiders in American culture. It is for the people, no matter what their beliefs, income, education, or place in life. It is very progressive, even evolutionary in many instances.
