Answer:
Many groups of people benefited from the establishment of British colonies in the Americas.
Step-by-step explanation:
The British Crown benefited because it obtained a new source of income, especially since it applied a mercantilist policy with the colonies, which allowed the metropolis to run trade surpluses with the colonies.
The founders of the colonies, and the subsequent elites of these benefited because they could obtain great wealth from what was essentially unexploited territory.
Finally, colonists/settlers themselves also benefited, by having a safe haven where to go if things in Britain where too hard for them. This is especially true since many of the British settlers in the Americas were either persecuted religious people, or poor peasants who had nothing to lose.
