How was the British policy of salutary neglect good for both the British king and the American colonies:

Economic profitability and greater autonomy of colonial institutions.

Explanation:

It is a policy pursued globally by Great Britain from the beginning of the century until the revolution. Customs supervision in the colonies by the British authorities was very flexible, but in such circumstances, the British had a secure income source that was economically viable for them. On the other hand, the colonists also benefited from such a situation. Less interference by the British authorities in the colonies' daily activities was an excellent starting point for launching revolutionary aspirations.
