What were the names of the two major domestic programs implemented by U.S. President Johnson?

Thank you LBJ for recognizing true issues and struggles that millions of Americans face. I wish you were still here to keep things on the right track. DJT thinks tax breaks for multi millionaires is actually doing the American people a favor and putting Elon Musk in charge of economic ideas which includes downsizing and/or eliminating these important programs is a great idea? Does DJT actually understand the phrase “Make America Great Again”? If he did understand it he’d go back and review JFK and LBJ’s plans for America. Then he might have an inkling of what truly makes America great.
