The correct answer to this open question is the following.
England made money from its colonies mostly by heavy taxation. For instance, the laws and taxes imposed by the British monarchies to the 13 American colonies were the Stamp Act, the Navigation Act, the Sugar Act, the Wool Act, the Quartering Act, Townsend Acts, among others. Of course, these laws angered the American colonist because they did not have any voice and no representation in the British Parliament. These heavy taxations were important causes that later derived in the Revolutionary War and the Declaration of Independence.
