Answer:
high taxation from the British government.
Step-by-step explanation:
The phrase 'all men re created equal' was included by the founding in the declaration of independence.
One economic cause of the declaration of independence is unfair taxation that imposed by the British to the colonists. At that time, British empire need to find a way to extract a lot of money to repay the cost that they spent in their war against France.
To cover this cost, They decided to raise taxes on various products that were sold by the colonists, making them loss a lot of disposable income. This contributed to the resentment that eventually made colonists support the independence movement.
