See, everything Jesus did was voluntary. Paying taxes into a government is involuntary, so actually Jesus would care very much. If we do exactly as Jesus and the Early Christians did, we would not be using government. If you have a problem with healthcare, Jesus said to solve problems first by going to the person, then to elders, then to the community, and St. Paul instructed Christians specifically not to use the courts of law to solve disputes among themselves. Trying to glom government programs onto the very clear words and examples of Jesus and the earliest Christians is like trying to fit a square peg into a round hole.
