Nah. Capitalism may not, in the strictest, theoretical sense, be an ideology. But it is, in actuality, an ideology. It is not simply an economic system, but rather, a complex ideological web, including an entire set of beliefs and principles about what reasonable behavior actually is. It is, however, an ideology that has a logical and economic foundation - however flawed that foundation and its operational reality may be.
My understanding of communism is fine. Not believing in the ultimate efficacy of your preferred system doesn't make me an idiot. But feel free to sling more mud, it makes you look great.
Capitalism, as practiced by humans, absolutely has ideals and principles. they may be implicit, and they may be foolish and dangerous to enact, but it absolutely does.
Even the basic foundational logical arguments for capitalism are rife with assumption, and, ultimately, opinion.
Will you rephrase that?
