That is kind of a misleading statement don't you think?
It's not very good to have a large amount of your system RAM being used while sitting at desktop. When you actually use a program that will need the RAM you will have freezing and stuttering in games and/or longer load times as the system tries to free up RAM.
Having a lot of free RAM is not a waste but rather an assurance that when you need it, it is there and your programs run smoothly in the process.
As for the OP situation, he does not have an issue unless he uses programs regularly that require more than his 70% of free RAM.

The OS knows which memory is use and which memory can be freed. When a process comes and requires memory, the OS will immediately start either moving the cache data to paging or dropping the data.
i.e. The OS caches Photoshop because you use it often. Suddenly, it identifies a process that is starting to use more and more RAM. The OS will just start dropping the Photoshop files it had cache. The difference to the end-user is negligible.
