Between 1965 (the beginning of LBJ's "Great Society") and 1994, welfare spending has cost the taxpayers $5.4 trillion in constant 1993 dollars. The War on Poverty has cost us 70 % more than the total price tag for defeating both Germany and Japan in World War II, after adjusting for inflation. Many believe that Welfare has destroyed millions of families and cost a huge portion of our national wealth in the process.
