Why is entailment bad for farmers like the cunninghams?

Entailment is bad for farmers like the Cunninghams because it restricts their ability to make changes to their land or assets, limiting their economic opportunities. They are unable to sell or make decisions about their property without consulting the family members who will inherit it, making it difficult for them to improve their financial situation or adapt to changing circumstances. This system can perpetuate poverty and prevent them from breaking free from a cycle of hardship.
