"Share your wealth with those less fortunate than yourself"
Jesus once told a rich young man to this in order to get into the kingdom of heaven. Jesus was answering his question on what he must do to get into the kingdom of heaven
Your question is quite similar to that of the rich young man.
That rich you man could not do this. Jesus then said that it was easier for a camel to pass through the eye of of needle than for a rich man to go to heaven.
Jesus indicated that the "highest commandment" or in other words the highest Christian action, is to love your neighbor as you love yourself" This does not mean you forget yourself as most Christian falsely believe.
He then illustrated how we should love our neighbor in the famous parable called the "Good Samaritan". In that story, a discriminated foreigner took complete care of an injured crime victim, who was a stranger to him. He even generously paid for the medical care needed by this victim
But America, many Christians say it is a Christian nation, yet it cannot approve universal health care for all its citizens. This is unbecoming Christian nation. Other countries even non-christian nations provide universal health care for all its citizens.
