I disagree. Not everyone wants to spend the time to completely customize their system. Distros like Manjaro and Endeavor give people a decent “just works” install while still giving them experience with the Arch ecosystem. The forums are usually a good resource, and everything on the arch wiki still applies. It might just be because I had previous linux experience, but I’ve learned a lot running Manjaro.
The average person is not going to jump straight into vanilla Arch as their first distro, but after a couple years with Manjaro, they might try it.

They were buying water from Detroit’s water system. In order to save money, they switched to getting it from the nearby river, but they failed to account for how the new water source would interact with their pipes. They didn’t treat the new water correctly and it corroded all their old lead pipes, dumping lead into the water and giving everyone lead poisoning.
Even years later, after they switched back to Detroit water, they’re still having problems because the damage to the pipes is already done.
