What does sacrifice mean to Congress?

President Obama is asking us all to sacrifice. Does this mean that the senators and Congressmen who just got pay raises will give them back? I know they are so-called "cost of living" increases, but who put them in the first place? The cost of living increased because of these same people not doing their jobs. A real Catch 22 - they cause the cost of living to go up, so they get a cost of living increase.
