Could you more clearly define the “presence” of S&T? Your examples like “automated farming tools are practical to obtain” sounds like a way of restating “both the availability of S&T and the economy are strong”, which does indeed imply that the economy will be strong, but “A ⇒ B” would have been a much more useful theory than “A && B ⇒ B”.
