This could be why we don't hear about it.
"As recognized by the World Summit, social development aims at social justice, solidarity, harmony and equality within and among countries and social justice, equality and equity constitute the fundamental values of all societies. To achieve “a society for all” governments made a commitment to the creation of a framework for action to promote social justice at national, regional and international levels. They also pledged to promote the equitable distribution of income and greater access to resources through equity and equality and opportunity for all. The governments recognized as well that economic growth should promote equity and social justice and that “a society for all” must be based on social justice and respect for all human rights and fundamental freedoms.Social justice is an underlying principle for peaceful and prosperous coexistence within and among nations. We uphold the principles of social justice when we promote gender equality or the rights ofindigenous peoples and migrants. We advance social justice when we remove barriers that people face because of gender, age, race, ethnicity, religion, culture or disability."
May will have to backtrack a lot on her ideas of human rights and fundamental freedoms.
