The growth of industries in America started in the earlier 1800s and continued all through to the civil wars. After the war was over, the industries in America had become small, and labor remained widely but limited the production of more products.
Many businesses operated in small companies because lacked enough capital to expand. The American industry changed drastically after the war due to the introduction of machines that replaced manual labor, thus increase production. Investors also improved and expanded their operations.
A.Respect existing colonies but not new attempts to control Latin America.
There wouldn't be a USA, and...
the Indians would still have pretty much all of the Middle-west of the USA.
Hawaii would still be under their kings/queens
Alaska would still be part of russia
China would pretty much never had any technological progress (they isolated themselves)
Japan would still be going around with pretty much katanas.
etc etc

<span>There were many ways Americans helped the war efforts. At some
point, people would let soldiers live in there houses, women would
work in factories to help war production, and many would give up
the nylons they wore to help the effort. </span>
