The American Revolution might not go very well at all.
First of all those two colonies were very wealthy so the british might not need to tax the americans at all. The sugar produced in both colonies was huge.
In that case is there even an ARW to begin with?
Without the Stamp Act and similar tax hikes (assuming Cuban sugar profits make up for the FIW debts) much of the casus beli for the common Yank is gone. Without the taxes you have no wanton acts of property damage requiring the garrisoning of redcoats. You still have the indebted landed gentry looking for a cheap way out of debt and you may still have a push for more regional autonomy. But other than a handful of Liberal fanatics the people at large don't have much reason to resort to arms.
Might we see a compromise over local autonomy issues? And might the gentry prefer to push for development of local luxury goods to break the "catalog luxuries" monopoly?
