Why did the younger sons of wealthy planters from the 1830s to the 1850s often live in rougher quarters than their fathers?

1. They deliberately rejected the ostentatious luxury of their fathers.
2. Planters as a whole during this time period lived much harsher lives than those who came before them.
3. They were self-made men who built their plantations from the ground up.
4. They were forced to move to the frontier and work on isolated plantations.
