"This is about the future. This is about bringing progress and prosperity to American families," he said. "This is about showing America and the American people that democracy still works in the United States."
The result of difficult negotiations with the right wing of the Democratic Party, the envelope includes the largest investment ever made in the United States for the climate -- 370 billion dollars to reduce greenhouse gas emissions by 40% by 'by 2030.
The second part of this major investment plan intends to partially correct the huge inequalities in access to care in the United States, in particular by lowering the price of drugs.
Medicare, a public health insurance system intended among others for those over 65, will for the first time be able to negotiate the prices of certain drugs directly with pharmaceutical companies, and thus obtain more competitive prices.
