I suppose it is "just" an ancient relic of a mentality.
How many kings built themselves this, that or the other in order to commemorate themselves?
We probably got some of our best architecture out of those kind of self-aggrandizing "idols", but nobody has the patience for it anymore or wants to see such wanton self-indulgence. I know I don't. Maybe I'd forgive Trump if he created something really impressive or useful, like they still do in places like Dubai, but yeah. Renaming shit, hanging pictures of yourself outside buildings, and modifying the pre-existing White House kinda shows he has no good ideas - he's just interfering in shit he should leave alone, I hope
@fedoriswar37 is right though and he's erased and forgotten as soon as the next President walks in.
