And the word of the Lord came again to Zechariah: "This is what the Lord Almighty said: ‘Administer true justice; show mercy and compassion to one another. Do not oppress the widow or the fatherless, the foreigner or the poor. Do not plot evil against each other.’
 — Zechariah 7:8-10
The Democratic party favors policies that reduce income inequality whereas Republicans do not since reducing taxes on the wealthy (the most favored policy approach of Republicans), according to the CBO research, is less effective than policies that directly help the poor and unemployed.
"Three-quarters of Democrats favor raising taxes on the wealthy and corporations to expand programs for the poor as the better approach to lessen poverty. Republicans, by about two-to-one (59% to 29%), believe the government could do more to reduce poverty by lowering taxes on the wealthy and corporations in order to encourage more investment and economic growth."
