Why aren't there tax breaks for the disabled?

the economy is bad i understand that and the goverment is trying to give relief to taxpayers with a little extra money this year,but they are not helping the disabled at all,most of them are on food stamps just to make ends meet.
they will not get any increase because the goverment decided to give it to the working class.
why do they not help everyone,no one decides to just wake up one day and say i think ill be disabled today.
