There is an evil strain permeating American culture and that is the culture of aristocracy. It has been eroding the egalitarian values this country was founded on. I fear liberals who believe that all humans are equal are loosing the argument by those that want to divide humans into class to protect the status quo. These aristocrats argue from the vantage point of power, that they are where they are due to some sort of superior character trait and it is equal opportunity that allowed them acquire their lot in life. This is misleading and people are falling for it. The poor are poor because they are lazy they say. They shouldn't have to work hard to support them. These are strawman arguments that don't address the socioeconomic condition that lead to and support poverty and the culture surrounding it.
There is no scientific evidence that some people are inherently superior to other humans. Superior in what way? The ability to indulge in selfish behavior in the pursuit of wealth? The ability to throw a football better than anyone? The ability to empathize? To create a fascinating work of art? Teach other humans? Make new discoveries? Higher intelligence? What decides if one is better than another: The subjective perspective of human beings. There is not an objective group of humans or even an individual that is superior or better than any other. It depends entirely on the context. It is subjective in nature.
I am a liberal and believe in the equality of all humans because we are genetically mostly the same. Even genetic differences don't indicate objective status stratification. We have more in common than uncommon. The differences are only exaggerated by the aristocrats who want to justify that they can rule over us by a position of superiority that they themselves define and a system they maintain. They want to keep their power and their wealth. They are anti-democratic. They are the new American aristocrats.
Say no to aristocrats as well as pseudoscience.
