interesting point of view about Jesus. However, I don't think he was talking to the government when he said "take care of the poor". He was talking to the future church.

The story is that he was talking to us, the people. The day when we are all part of the "future church" has not arrived, but we do all pay taxes (yes, we all do) to government, and government is supposed to use some of the tax money to take care of the poor.

Simple enough.
