I think one of the central theses of the book is that when a new freedom is gained some measure of security is lost and there can be a backlash as society attempts to restore the lost security, unsuccessfully because liberties, once gained, are hard to lose.

I don't recall putting is as bluntly as "people want to be enslaved", but if you had to summarise the argument in 5 words I guess that would work.

A book about people who want to be enslaved is Bob Altemeyer's The Authoritarians which is available online as a PDF and has been discussed before on ET.
