broligarchy

This is a combination of bro and oligarchy.  Weirdly it comes to us from the surfing world of 2000 when broligarchy was used to describe the group of surfers who controlled a break.  Broligarchy became mainstream with Trump who, in his second term, appointed a group of rich men, mostly from tech companies, to various positions of power within his presidential coterie. They are also referred to as tech bros and form the tech oligarchy.  It remains to be seen how long the broligarchs will find favour.
