Many colonists had become wealthy at a time when Britain did not have much wealth.
1. Colonists wealth: Because of lenient taxes before the start of British taxes, and the payments Britain made before to to-be-colonists to move away, as well as the finding of material wealth in present-day-USA, colonists were much more well off then the British.
2. Heavy taxation on the people living in Britian: The citizens in Britian were already paying large amount of taxes, and could not sustain more taxes on themselves, leading the British to think about their colonies.
hope this helps
