Electricity
the land was smooth, so it would be easier to build factories.
Factories, mines, lumber camps, ship builders, train locomotive manufacturers
Factories need transportation to bring in supplies needed inside the factory and to ship what is produced in the factory out to stores, the public, etc. Early factories didn't have the use of railroad and trucking transportation, so the quickest way for these early factories to bring things to the factory and ship goods out of the factory was by water. Therefore, they were built along waterways like rivers.
At first water power was the primary power source. Factories were built on the banks of rivers, and huge water wheels driven by the flow of the river would power the factory. Then the invention of the steam engine made it possible to build factories almost anywhere, and steam engines replaced water wheels as the primary power source in factories.
People in south America build dams on the major rivers to get more electricity. Plus, there is more industrialization in the area.

You would want a flat laid out area with rivers and streams nearby.
Imports were predominantly collected on manufactured items that competed with American manufacturers' products, thereby allowing the domestic manufacturers' to charge higher prices than would have otherwise prevailed. This was resented in the South, which had almost no factories.
Of course there are glitter factories...how else would it be made?
The plural form of factory is factories.
Closing the factories down would definitely do that.
Usually kids worked at factories, and the machines would hurt them and sometimes could kill them. For example if you had a loose clothes it would pull you in . It really depends on what factories.
