What is "progress?" I wouldn't consider Biden to be making progress if the overall trend is still negative, and the root cause isn't being addressed. To be somewhat fair, I don't believe the Democrats can do what needs to be done while maintaining their position, similar to what is happening to the Labor Party in the UK from its conception to now.

Historical progress is relevant because it is a good indicator of what people were fighting for and against. The French Revolution was progressive against the Monarchy, even if the resulting French society would not be considered progressive today.
