"folder security permissions not inheriting on child folders and files is still probably broken like in windows 7"
This has never been broken as far as I know. You realise inherritance can be deliberately disabled? I suspect the actual problem is somewhere between your chair and keyboard...
"administrators group overrides authenticated users, and users,"
No, it can coexist as a separate permission. It doesnt override anything.
"you should`nt need one or the other or both"
Yes you should for a secure system. Admin / root rights should always require a different account from your normal use.
"take a new install, and program files, add administrators to the audio and ownership, and then administrators group to all child objects,"
Works fine for me. Adminstrators group has access to the Program Files folder by default though so you wouldn't need to add it unless you already screwed something up...
"and all permission will be broke in windows 7"
I assume you mean broken. Broke as an adjective only means out of money!
