Which of the following explains why colonists chose to use slaves rather than paid workers? there were not enough paid workers to transport from europe. they did not need to pay slaves so their profits would be higher. they were unsure of where to find paid workers who knew how to grow crops. there were laws governing how many hours per week paid workers could work.

an effect of the steamboat's popularity was that people began building canals in the united states and europe. this was done to find another way to transport goods across the country and in that time, transportation using the river was very slow and dangerous. it depended entirely on manpower and the current of the river. that all changed in the late 1700's when steamboats were introduced. they soon revolutionized travel and trade through the river and dominated the waterways. eventually, other means of transportation took over from the steamboats, but there was a time that they the united states to expand to the west.
