Why does gov't have to get involved, add their beauracratic (sp sorry) layers of EXPENSE and ENTITLEMENT (I'm talking gov't employees here) to do what we already can do with our local communities, charities, churches, etc..???? This 'spread the wealth' concept makes no sense. It will cause people to hoard and compete. Free will allows people to follow their hearts and dreams and they can and often do, more than than what they think they are 'able' to do.
So you really believe gov't has to tell YOU what to contribute? You aren't capable of making your own choices to contribute in your own ways? Ohhh, you are probably worried about those people who don't want to give anything to anyone, right? Well trust me, I know more generous, giving people than tightwads, and their incomes (which vary widely) make no difference in their generosity.
On the other hand when you have more wealth, you have more ability to give. Sure, not everyone does it but so what? Look around your friends. What kind of people are they? Those are the kind of people that make up the bulk of our society. Not the few you are worried about.
