I've held for several years now that any -ism term generally does more to obfuscate than it does to elucidate. And capitalism and feudalism are among the worst terms in that regard, as the former can mean anything from "money exists" to very specific ideas about how the government should regulate the economy (or more accurately, how it shouldn't), while the latter is generally a vague reference to Medieval Europe without recognizing that there was actually quite some diversity in political and socioeconomic conditions across time and space in that 1000-year period.
