Now I am not wealthy by any stretch of the imagination but I do not have a moral obligation to force anyone rich or poor to provide essential healthcare. I could morally encourage people to donate time and money to hospitals as a charity but to force them as part of a government mandate to me is morally wrong.
If you think that taxing the wealthy to provide essential services to the poor is immoral then you've totally lost me. That's not the type of society I want to live in. Relying on voluntary donations leaves too many people to fall through the cracks.
The problem with using words like wealthy are that it is a moving target. Generally when someone says wealthy they mean anyone making more money than them. In a small town in south east U.S. 150k would make someone very well off. One might even say wealthy. In San Francisco someone making that amount of money might be homeless. So should the person living in California pay more?
