I don't think liberals care about those in unfortunate circumstances to the point that they want to personally help. I think they just want the problems in society to go away, so they shift the burden to government where they don't have to worry about it. In their own world-view, all problems that require direct participation, by which to solve, belong in the hands of the government so that the individual can be free of these considerations. Additionally, I think the liberals, subconsciously, want to be free from all requirements that nature imposes on us, so they are more than happy to renounce their need to acquire material possessions to support their life, believing that if the government divided up all the wealth in society, and had a plan for each problem that nature imposed on people, then each person then has the ultimate freedom to do what he chooses without considering the consequences, or the responsibility. I think this is why many of them believe they are liberty minded.
