The raising of the real wage of England (due to the shortage of labour as a result of the reduction in population), a trait shared across Western Europe, which in general led to a real wage in 1450 that was unmatched in most countries until the 19th or 20th century.
The correct answer is The colonists could export goods only to Britain.
When the American colonists were under the control of Great Britain, they were under the influence of a mercantilist system. This economic system was created as a means to to benefit the mother country (England) by gaining natural resources from North America and developing a favorable balance of trade. Essentially, the colonies economy existed to solely benefit the British.
This severely limited the American colonists trade with other countries. This angered colonists at different times, as they felt it was an unnecessary constraint implemented by the British government.
