As shown with above. Nostalgia and reality are two very different things to mistake for the same thing. Times are always changing. Just because it's different from what you know doesn't mean it's any less valuable and has something else to offer.
Personal opinion here: Tarantino fetishized the Golden Age of Hollywood back when he believed things were better for him, when things made more sense on his terms. He mistakenly believes that times were simpler then, and they weren't. They were only easy if you were allowed it
