ELI5: Why is a password managing program recommended for extra password security? Doesn't that just give a hacker a single place to get all of my passwords at once if they get through?

Password managers are useful because they can allow you to use much more secure passwords as opposed to passwords that are easier to remember and, probably, easier to guess.  It means that when as password database gets stolen, it will take significantly longer for brute-force methods to get your password.

It's safer because when people are looking to break into accounts they generally don't care which accounts they get.  They just run the whole list looking for people who did use easy passwords and then seeing what they can steal from the related accounts.  They're not targeting you directly.  Someone who is targeting you directly and get can get access to your computer (either physically or via the internet) with enough access to do something like steal your password manager file will probably be able to circumvent any passwords you chose anyway.  

Even if they do get the file, most password managers use *very* robust encryption.  For example, 256-bit Twofish (like is used in Password Safe) is essentially impossible to break on any meaningful timeline even with massive computing resources.
