These writers REALLY love to reuse material. If you look up stuff like what was happening in the leadup to the Great Depression, it sounds eerily familiar. The stuff in the Gilded Age is shockingly similar to what we see going on today. And go lookup how Hitler swayed conservative Christians (including Catholics). It sounds like stuff that could have been written yesterday. Oh and LGBTQ hate? Nothing new. LGBTQ people were literally one of the first groups the Nazis went after.
But that whole thing also gives hope. Such evil has existed before and been overcome. It can be done again. It also often falls because of its own stupidity.
