Step-by-step explanation:
The Louisiana senator who gained substantial support for his "Share Our Wealth" program was Huey P. Long, also known as the "Kingfish".
Long proposed his Share Our Wealth program as an alternative to President Roosevelt's New Deal. The program aimed to redistribute wealth by liquidating large personal fortunes and providing direct payments to less fortunate Americans. Long promised to give $5,000 to every family, $2,500 to every worker, and also proposed elderly pensions and education funds.
Although Long's program was criticized by economists for its unrealistic math, it garnered significant support from over four million people before his assassination in 1935.
