Most of my friends are liberals, so I can't seriously make sweeping generalizations about liberals. It's not possible. One thing I have noticed, though, is that for many of them, their normally cheerful dispositions get downright ugly when it comes to seeing or talking about "rich" people.
At first I thought it was because they hated the idea of wealth, but I learned that's not true. They all would love to live in expensive homes and drive expensive cars, fly around the world in private jets, and generally live the Lifestyles of the Rich and Famous. (One friend has been living that lifestyle, but without the income to support it).
They want the goodies, but they don't want the work that getting the goodies requires. So, if they can't have the goodies, they don't want someone else to have them either. The goodies remind them that it's possible to achieve just about anything if you work hard enough, and my friends just don't want to work that hard. It's not about redistributing wealth, it's about redistributing misery.
