I have always disliked party politics, for your rep could not vote for a bill if it was good for his area unless his party was in favour of the bill. Same reason I dislike debates, one side is completely right and the other completely wrong. There is never any give and take.
There is also another possible reason for middle class! The Bubonic Plague (or Black Death)! There were so many deaths, that skilled labour was hard to find, increasing the rate of pay for the skilled labourers. Another possibility is that many of the Lords died, basically leaving lowly peons in charge of their own farms, owing nothing to anyone save themselves. They were lower than the Lords, and higher than the peons working some Lords land.
I tend to agree with the quote. If you look at your life as a string, part of which is the past, one point being the present, and part of it leading into the future. No part of the string is larger than any other. No part lasted longer than any other. (true there are two points of value, the beginning (birth) and the end (death) all other points are equal in value)
I, personally, do not see what middle class has to do with politics. It seems to me that middle class came about due to the industrial revolution. Some people had enough money to own the new machines (upper class) but they needed people to maintain/operate the new machines. These people needed more education thus were paid more, which created a middle class. Lower class people (people who were paid less) were the normal uneducated folk who did manual labour.
It may be indispensable for a thriving economy, but why would anyone think it is necessary for democracy? It seems to me that a democracy (present day democracy) is based on all people have an equal say on who governs them and what direction the government leans.
