The main purpose of the Land And Social Security Optimization Act, also known as the LASSO Act, is to enhance the funding of the Social Security Trust Fund by allocating a portion of the revenue generated from public lands. This aims to provide additional financial support to the Social Security system, which is crucial for retirees and survivors. The key provision of this legislation mandates that each year, 10 percent of the revenue collected by the Department of the Interior and the Department of Agriculture from certain public lands will be deposited into the Social Security Trust Fund.
