Actually, if you really study the history, it was not so much a question of being overburdened with taxes as it was an issue of self determination and plain old obstinacy (on both sides). The taxes as passed were really not that onerous. In fact they were far less than what the citizens in England were already paying. I may have the sequence out of order, but I am pretty sure that the tea tax had in fact already been rolled back. At any rate, most of the taxes were in fact ineffective. The actual match that lit the fuse, as it were, was more an issue of smuggling in New England being sharply curtailed as a result of increased British enforcement.
I'm certainly no history expert, but I have read and continue to read extensively of that period of history. If we are to understand the documents and ideals foundational to our country and our constitution we need to understand the writers of those documents, and the times they lived in. It is only when we have done this that we can hope to understand where we should be going.
Otherwise a very good post openmind! :D
