Again I think you had a situation where straight sci fi cinema just wasn't having any money put into it in that era and instead a lot of the ideas/talent went into films that could be sold as action.
The idea of the "Reagan actioner" to me never made sense either, almost all of these films like Predator, the first two Robocops, Total Recall, Cameron's Terminator's, Aliens, Running Man, etc actually have a strong anti establishment bent to them. Ironically its during the Clinton era that I think action cinema lost its political edge and became full of rah rah nationalism and praise of the US establishment.
