Or, to put it another way (but in the same derogatory vein) - those who value individual selfishness - "what's mine is mine and screw you" and those who feel that the individual, as part of a society, has a responsibility for that society.
That is an incredibly intellectually flawed argument. Everyone is entitled to what they rightfully earn. That is the very driver that breeds success and innovation. Nobody is going to go the extra mile if they aren't going to reap the rewards for doing so. It's basic human behavior and has been observed and proven time and time again. Collectivism only results in the halting of progress.
Nobody is entitled to take something of someone else's just because they may have more and think it's unfair. That attitude is childish and a trait of somebody emotionally weak who refuses to take responsibility for his own life and instead just blames somebody else for his failures.
If you feel that you have a responsibility to society then nobody is stopping you from helping society. Nobody is stopping you from being charitable to others. That doesn't obligate anybody else to engage in the same level of charity as you just because you think they should. The idea of America is that it is a nation built on individual freedom and liberty. That means that I have the right to spend a day helping build a Habitat house, which I do twice a year. It means the Levines, the wealthiest family here in Charlotte, have the right to donate millions of their personal fortune to public causes around the city. It also means that people like Ebenizer Scrooge have the right to keep every penny they earn and not give it out to anybody if that's their decision. It's not your decision. Your view doesn't promote liberty, it impedes it.
A clear and concise explanation of the differences between True Conservatives/Libertarians and the Collectivists/Statists who masquerade as Democrats and Neocon Republicans.
