To many, 'welfare' is a word with negative connotations now because of the media coverage that lead to welfare reform.
They coined the term "welfare-mom" and reported that unmarried teenagers were draining the government coffers. The politically correct word for a time was "Aid to dependent children." Then it changed to TANF.
"In 1996, President Bill Clinton negotiated with the Republican-controlled Congress to pass the Personal Responsibility and Work Opportunity Act which drastically remade the program. Among other changes, a lifetime limit of five years was imposed for the receipt of benefits, and the newly-limited nature of the replacement program was reinforced by calling AFDC's successor Temporary Assistance for Needy Families (TANF). Many Americans continue to refer to TANF as "welfare" or AFDC."Ref. en.wikipedia.org
