Moving objects together same as in a hierarchy (parent?)

LOL - don’t get me started, lest I get attacked by the BlenderHeads again.

I posted this video almost 2 years ago and got raked over the coals in the comments:

I don’t know how much has changed, but just wanting to do SIMPLE parent/child grouping turned into a confusing mess. I think maybe there’s now an add on (Blender seems to need a ton of these VS having it built-in by default) but honestly, I haven’t made the time to try and figure it out. It’s this constant love/hate with Blender - i love Eevee and some of the hard surface modeling add ons, but the backwards navigation and lack of basic functionality drives me insane at times.
