Q&A: why losing the Thirteen Colonies did not ruin Britain

Why did the British economy not collapse after losing the Thirteen Colonies?

Because Britain's economy was far less dependent on those colonies than French planners believed.

The answer directly challenges the French expectation that American independence would cause Britain's collapse. The British economy was not as dependent on colonialism, or on those thirteen colonies in particular, as French policy assumed. Losing political control therefore did not remove the whole commercial and productive base of British power. The brief exchange supplies an economic reason why French strategic forecasts proved too optimistic.
