Unfortunately, the elected officials in charge of changing the rules can get more votes by talking about other wedge issues. Worse, some of them can even get votes by peddling the myth that the poor are the ones responsible for bleeding the working class dry. This is often accompanied by a "fix" that costs more than it saves, makes life even harder for those at the bottom, and sometimes even funnels money back into the party / official's pocket (e.g. the urine test performed by a company owned by the official's wife).
It's voters that need to change, not social workers.
