I am reading a book and it says
The new Unemployment Insurance Act, 1971, differed little from the White Paper, which contained the legislation's philosophical roots.
Source: Pal, Leslie A. 1988. State, Class and Bureaucracy: Canadian Unemployment Insurance and Public Policy (p42).
What does "roots" mean here?
Does it mean "ideology", "tenets", or "values"? In that case, is the following the right interpretation?
The white paper laid out the core philosophical tenets that led to the new act.
It seems to serve no real purpose in the sentence except to really be just annoying and cryptic. Why not use a clear word like the ones above if that is what the author means (rhetorical question).
"Root" means "the origin or source of something" (Cambridge).
"A white paper is an authoritative report or guide that informs readers concisely about a complex issue and presents the issuing body's philosophy on the matter. It is meant to help readers understand an issue, solve a problem, or make a decision." - Wikipedia
