Consider when central banks and income tax were introduced, also look into changes in both education and welfare in various countries around this time.

Obviously I don’t know for sure, it’s not like there’s minutes from the meetings of the parasite class of the time that we can cross reference here. But a lot of ‘infrastructure’ was put in place at that time that would inevitably lead to centralisation and big government.

There’s a lot of dots that connect but I’ve not had the time to read enough of the background to really see how plausible the theory is.
