My take is a bit different to yours. I think they didn't anticipate a concerted effort to undermine like-mindedness of the people comprising institutions in an attempt to make an egalitarian society. It's not that long ago that people appreciated the difference between social exclusion and custodianship, and recognized that some amount of gatekeeping is essential to institutional function.

To be clear, that same gatekeeping can be and has a times been perverted into social exclusion, but the problem at hand IMO is the discarding of the baby with the bathwater.
