Why have many US farmers lost their farms over the past 40 years?

Many US farmers have lost their farms over the past 40 years due to a combination of factors, including rising operational costs, fluctuating commodity prices, and increased competition from larger agribusinesses. Additionally, changes in agricultural policies and trade agreements have affected profitability, while environmental challenges and climate change have further strained resources. Access to credit has also become more difficult, leading to financial instability for smaller farms.
