Benjamin Dueholm highlights it:

While staunchly, even aggressively re-asserting Catholic teachings on homosexuality and birth control, he preached a recognizably left-wing version of economic justice. And while reiterating the special status of his church and his faith, he opened his rhetoric—much more than his predecessor did—to the reality of a pluralistic, secular Europe.

In countless speeches and letters, Benedict expressed an economic ethic that Fox News would label socialistic. In just that one address to the diplomatic corps, for instance, Benedict stressed the importance of universal education; the need for “new rules” stressing ethics over balance sheets to govern the global financial system; and the importance of fighting climate change in tandem with global poverty.

But this has been true of every Pope in modern times, including John Paul II whose brutal critique of communism was always accompanied by a dismay at the materialism of capitalism.
