Taking out ALL the fraud would seem to be the best first move,altho not a full solution. The problem with this comes in when everyone has their own idea of where the fraud is. Politicians & bureaucrats can kick this can down the road no longer.
I am not, not, not against getting rid of fraud. But it's delusional to think that doing so will do any more than postpone the inevitable by a few years.
Of course, those who think that that postponement will cover them for the rest of their retired lives are probably fine with the idea.....
