That is very hard to believe. Jesus was very interested in social reform.
Where does he set out his schemes for social reform?
Where does he say people should organize to achieve such and such results in society?
Where does he say how society should be governed?
As far as I know, the teaching of Jesus we are given is more along the lines of personal ethics. I guess "personal ethics" if followed could play out to result in social reform, but it's far from clear (to me at least) that Jesus had such a vision.
Remember, the gospel is good news for the poor.
Jesus could have "cared" about the poor, without having a vision of social reform.
The gospel is not only about "going to heaven when you die" - it is news of a new kingdom here on earth with Jesus at the head. So, of course, this new kingdom shapes the social landscape. Or it should, at least.
You are probably aware that one strand of thought in the study of the "historical Jesus" is that he was an "apocalyptic prophet". As a fan of NT Wright, you reject that picture. But if it's correct, then the idea of the "kingdom" that Jesus had would not fit with him being interested in social reform.
