It's not my perspective, it's the history of the U.S. the idea was those agreeing to taxes would be those actually impacted by taxes. Sort of defeats the purpose of freedom of at any given moment everything you worked for can be taken away by a group of people, simply because they out number you. There are counter arguments to this but it's not simply to say well that idea is dumb or mean.
