Answer:
plentiful goods, cheap goods, more jobs
Explanation:
The paragraph is organized in a way that the pros are listed first, first the author mentions the "greatest positive result", plentiful goods. This first advantage lead to the second one, as the goods were more available they became cheaper, so cheaper goods is the second one. The third one is derived from the previous ones, as more goods were produced and bought, more factories were needed, and more jobes created. This is the third possitive aspect.
The word "unfortunately" is used to start the list of the cons.
