In reality, these laws passed by government were only helpful to the government members since most of them were landowners. They wanted to earn more (money made/good thing received) from increased corn prices and not having to buy corn which they can help grow on (more than needed) land and sell it themselves. However, since most of the old England lived in cities, they had no land to grow the vegetable and depended on buying products (that are bought and sold). This is why (related to elected lawmakers) (people in charge of something) were unwilling to revise the law.
In 1828, the Duke of Wellington's government changed/redone the Corn Laws and they made a sliding scale for the weight-to-price of the corn. This rewriting/redoing still did not help the residents of old England since the price was still high.
