The correct answer is "talent, hard work, and character."
Northerners saw a person's success as based on talent, hard work, and character.
The reason why northerners had this idea is that they were dedicated workers that knew how to make a living through hard work in the industries. They built fabrics and created businesses to improve their economic status.
Let's have in mind that the North opposed the use of slavery in the South. Northerners saw slavery as an immoral and unjust practice, and the North believed that slavery prevented the South from using modern farm equipment.
The people from the Northern states supported the end of slavery. They considered that slavery was an immoral and unjust practice. The Union states considered that slavery should end. But the Southern states relied too much on slavery to maintain a good economy. So that is why they justified slavery. It was a means to maintain their wealth.
