I’ve been a “rich liberal” by that definition some years, and not others. Why? Because I’m often “rich” by your provided definition, and I’m liberal.
The reasons why I’m liberal aren’t really affected by my income. I’m in favor of social and civil rights for everybody, the curtailing of religion in government and the curtailing of government interfering the in the religion of individuals, free speech, all that stuff.
I believe that “Big Government” is too often conflated with “Wasteful Government.” I want my government big: it’s the only organization of the scope necessary to provide health care to an entire country, provide services like schools, police, fire, infrastructure, etc. that have no “free market” way to fund themselves, and when unemployment is high, it can be the employer of last resort to do all those things.
I believe that the reason more people aren’t “successful” isn’t because of widespread laziness (and definitely don’t believe that “laziness” is caused by skin color or what papers you posses), but because there are so many obstacles that can completely devastate a poor person trying to rise, but are almost unnoticeable to rich folks–to the point where “we” forget these obstacles exist. The purpose of government should be–before anything else–to provide sufficient nets to allow anyone facing such obstacles to overcome them and return to productiveness. And frankly, I don’t care if that means a small percentage can live in borderline poverty without working. Why should I? They don’t add up to enough to matter.
Furthermore, I understand that these things take money, and that in the United States, that means that the wealthy (including me, if I’m “rich”) and corporations are going to have to be the ones to pay a high percentage of the costs. I’m really OK with that – too. The sorts of tax increases we’re talking about aren’t going to change the lifestyles of the ones we’re “taking” it from, but they’ll make a huge difference to the country.
I disagree with many liberals (and conservatives, for that matter) on a few things: I see unions as a necessary evil rather than a relatively universal force for good; I think the US should join the rest of the world and completely eliminate the tax on money earned outside the US (both for citizens and corporations. I want Apple’s money, for example, back in the US and being spent a LOT more than I want to double-or-triple-tax them on it.) I frankly don’t consider an American’s right to a job to be greater than that of someone in another country, and that we need to put a lot more effort into being citizens of the world than encouraging us-or-them policies.
I propose that policy should be set based on facts and evidence rather than religion, opinion, and discredited economic voodoo.
Little or none of this is based on my income level, though.
