The creation of military bases impacted South Carolina as:
led to a decrease in cotton prices
forced more people to participate in the draft
Step-by-step explanation:
The effect of military bases are sometimes unfounded and unexpected as there is a real sense that they might help the economy but they can also fend off the investors that would then invest in places with less place for the military operands.
Thus, that is what happened in the state
There were also a few good parts to this though which were that more people in the state were inspired to go for the military draft there.
