The reason why this “colloquial definition” is this way is so that capitalists can convince the masses that capitalism is natural “because it has always existed” by claiming that antique slave society, feudalism and even late hunter gatherer society were actually capitalist. This isn’t a neutral definition that is as valid as the other, it is a lie crafted for propaganda purposes and shouldn’t be taken seriously.

Most books by Ha-joon Chang, especially 23 things they don’t tell you about capitalism. Fun fact, Ha-joon Chang isn’t a Marxist, he’s a liberal, but his writing is still critical enough of capitalism that South Korea banned his books.

Anything on prolewiki’s library are good reads as well.

For a broad look at the evolution modes of productions and how capitalism came to be there is this 60s textbook from the soviet academy of science, there even are a series of videos following the textbook by the finish bolshevik that is pretty good.
