Here is a thread that explains the three bills and why the reforms will benefit the farmers. This comes from a joint article with @RashiShar11 on the issue.
"The agriculture sector has a huge number of small and landless farmers. These farmers produce little marketable surplus, that is, additional produce that could be sold in the market to generate income."
There exist feudal production relations in Indian agriculture.
"The big landowners are often also the money lenders to small farmers, acting as the suppliers of seeds and fertilisers in the region. They play a disproportionate role in the government-regulated markets—the Agricultural Produce Market Committees (APMCs)."
"The big farmer produces excessive marketable surplus and thus benefits from the increase in minimum support prices (MSPs). The control over markets tends to create a system of exploitation of small and landless farmers."
"Food security concerns should no longer be the sole objective behind our agricultural policy. The new laws precisely mark this shift."
