Connection with Ballard's 'High-Rise'/Class Attack?

I'm in the midst of reading JG Ballard's novel "High-Rise," and can't help but see the incredible similarities between its story and "Shivers." Seeing that Cronenberg is familiar with Ballard's work ("Crash" being the bext example of his knowledge), has he ever mentioned "High-Rise" as a source for "Shivers'" story?

Also, I noticed another discussion on this board pertaining to "Shivers" being an attack on the bourgeoisie (and this possibly being incorrectly defined as the upper-class). Ballard's novel can certainly be read as, at the very least, an attack on the middle-class's desire to contain itself from the other classes, and "Shivers" seems to have a similar pretext. The apartment complex in both narratives are basically gated, integrated communities filled with relatively well-to-do white people (although Ballard's has a literally rising caste system). The fact that Cronenberg's story includes not only sexual debauchery as a point of anxiety/destruction, but that this debauchery is introduced from an outside source (a monstrous, genitally formed parasite), further solidifies the argument that "Shivers" is indeed making a statement against a privileged and contained class system, whether this statement was intended or not.
