Monarchy to Democracy

"The ideas of the ruling class in every epoch the ruling idea i.e. the class which is the ruling material force of society is at the same time its ruling intellectual force. The class which has the means of material production at its disposal, consequently also controls he means of material production." This quote seemed pretty simple to me, meaning that the upper class who has the money to control material production  also decides what material will be available and so is the ruling intellectual force. However, the quote became more complicated when we started to talk about the colonization of america and monarchy and democracy. If "each new class puts itself in the place of the ruling class before it" how is it that a change in government can occur. I thought maybe in this case it was because the monarchy of England was so far removed form the colonies that the colonists were able to see a problem with the system.  Also both the colonies and England had control over making necessities for each other; both were dependent on one another. I think that this special situation is what made it possible for the transition from the colonies to go from the class dominated by England's production to the one ruling its own ideology and production. It is true to say that material things affect out ideologies and so the production of a ruling class is bound to control the dependent class. I thought it was interesting that there is a way around this like in the case of the Revolution.
