If you take a look at Western language - or at least language that is idiosyncratic to the United States, you start to find that there are so many common expressions that make use of the disparagement of socially weaker peoples to provide their punch. I'm thinking here of expressions like crazy, dumb, stupid, insane, and etc. There are many more, and if you start digging further there are all sorts of sordid histories that can be unearthed.
Behind the language is a general pattern of antagonism and a need to rise to prominence while pushing others aside, a need which is not often misplaced, as the others that need to be pushed aside did the exact same thing prior, and then continue to hold their dominant position, stunting those around them.
It isn't just the language; many of our most central and well-worn technologies and institutions have their genesis in war and conquest, or otherwise general extraction, such as the multitudinous petroleum technologies we regularly make use of.
Because everything takes labor to produce, and then when it is produced, it is much easier to continue using it, as opposed to fashioning an alternative product out of scratch. What you use has a certain nature to it, which is taken from its process of production, and then what you use can transfer that nature to you as well. And production is always seeking to increase itself as it is.
It is very difficult to escape this kind of dynamic. It takes enormous amounts of work and time, for one thing.
