Christians and Poverty (social justice)

During the previous election cycle, I spoke with many people about voting for Christian values and unfortunately, many no longer consider pro life and pro traditional marriage as “the most important” or “only issues”. When confronted with what the Bible teaches on the subject, the most frequently used argument is some form of social justice. Are Christians not supposed to take care of the poor and needy of society? Did Jesus not do that when He ministered on this earth? Does Saint James not speak about taking care of widows and orphans?
