One of the biggest problems with television is that some of the worst showrunners imaginable are constantly being elevated. There's an over emphasis on trashy, bottom tier #content which is designed specifically to get black women or gay men to hype the shows on social media. The popularity of reality TV has clearly influencer scripted shows. The writers are then tasked with creating similar dialogue, fights/confrontations, etc to go viral. Creating a good show is largely irrelevant. Creating a show that stirs online engagement is what matters. Even if people hate the show, they're going to watch so they can shyt on it online. The Velma show, which looks incredibly like this Good Times remake, used the same blueprint and got renewed for a second season.
In terms of the portrayals of lower income black people...sure you want more diverse writers involved but I don't think that's the biggest issue. You don't need black writers exclusively to write black characters. The writers just suck, man. Young writers who don't research topics or themes beyond a very-obvious parsing of twitter for ideas. The days of well read young TV writers are gone. You just need to know how young people talk now.
