Why did colonists object to the tea act? because it would aid a different part of the empire than their own, colonists felt that
this was the kind of discriminatory action that violated the concept of liberty. it granted a monopoly, and the colonists opposed all forms of monopoly. the british east india company made inferior tea, and colonists preferred not to drink it. it raised the tax on tea so much as to make tea prohibitively expensive. by paying it, they would be acknowledging great britain's right to tax the colonists?
The colonists objected to the TeaAct, because they felt as if it was like the other taxes which were imposed on them by the British government. They had no representation in Parliament to defend themselves and were thus forced to comply with any taxation measures the British monarch felt was necessary to impose on the Thirteen Colonies.
