Why did english colonist in north america seem satisfied with their place in the british empire before 1763, but unhappy and rebellious afterwards?

I believe it's because the British Empire inconsistent treatment.

At first, British empire treated the colonists fairly and both of them developed a mutually beneficial relationship with one another.

After 1763, the British Empire issued a regulation that banned the Colonists to issue their own paper money, which make it realy hard for the colonists to pay off their debt.
