Yes, insofar as it is befitting a just economic system that benefits the hard-pressed and the down-pressed in their need. This conforms to the broad Christian tradition and is part of the historic Christian ethic.
While I'm not Roman Catholic, the Catholic Church's Compendium of the Social Doctrine of the Church has some relevant material in this regard:
"
Christian tradition has never recognized the right to private property as absolute and untouchable: “On the contrary, it has always understood this right within the broader context of the right common to all to use the goods of the whole of creation: the right to private property is subordinated to the right to common use, to the fact that goods are meant for everyone”[372]. The principle of the universal destination of goods is an affirmation both of God's full and perennial lordship over every reality and of the requirement that the goods of creation remain ever destined to the development of the whole person and of all humanity[373]. This principle is not opposed to the right to private property[374] but indicates the need to regulate it. Private property, in fact, regardless of the concrete forms of the regulations and juridical norms relative to it, is in its essence only an instrument for respecting the principle of the universal destination of goods; in the final analysis, therefore, it is not an end but a means[375]." -

Yes. I'm a Christian, I couldn't call myself a Christian if I didn't believe in social justice, it would be an oxymoron to say I believe in Christ and the Holy Scriptures and then reject the entirety of what the biblical message says in regards to justice and the poor.
I believe liberation theology (whether black or otherwise) communicates the good and just implications of Christian teaching and how it relates to the oppressed and the least of these. So yes.
