Efforts to restore a viable balance by reappropriating a sense of the common good and social solidarity have marked Western history for the last couple of centuries. In Europe such efforts were spearheaded by Catholic social teaching and democratic socialism, whose political expression in Christian Democratic and Social Democratic parties created the decent societies that have marked the recent history of Britain and Western Europe. When the present Pope in his last year as Cardinal Ratzinger met with Jürgen Habermas, he expressed his sympathy with the tradition of social democracy and said that it was similar to Catholic social teachings. In its fullness that is surely the case, but when American Catholic ideologues reduce Catholic ethics to an exclusive concern with abortion and gay marriage they take the social out of Catholic social teachings and become spokesmen not for the authentic Catholic tradition but for a narrow quasi-Protestant sect."
Meaning, they "American" Catholic "ideologues" are not socialist enough on other issues.

Ratzinger has even referred to himself as a "Democratic Socialist"
They - the Catholic hierarchy - are not opposed to greater Federal power over our lives at all, for any reason, outside of "right to life" issues.
And, the ONLY reason the USCCB opposes Obamacare at the moment are exclusively “right to life” issues. There are no other Marxist intrusions in Obamacare that they object to.
